Lucene contrib change Log
For more information on past and future Lucene versions, please see:
http://s.apache.org/luceneversions
======================= Lucene 3.5.0 ================
Changes in backwards compatibility policy
* LUCENE-3446: Removed BooleanFilter.finalResult() due to change to
FixedBitSet. (Uwe Schindler)
New Features
* LUCENE-1824: Add BoundaryScanner interface and its implementation classes,
SimpleBoundaryScanner and BreakIteratorBoundaryScanner, so that FVH's FragmentsBuilder
can find "natural" boundary to make snippets. (Robert Muir, Koji Sekiguchi)
* LUCENE-1889: Add MultiTermQuery support for FVH. (Mike Sokolov via Koji Sekiguchi)
* LUCENE-3458: Change BooleanFilter to have only a single clauses ArrayList
(so toString() works in order). It now behaves more like BooleanQuery,
implements Iterable<FilterClause>, and allows adding Filters without
creating FilterClause. (Uwe Schindler)
* LUCENE-3414: Added HunspellStemFilter which uses a provided pure Java implementation of the
Hunspell algorithm. (Chris Male)
* LUCENE-3445: Added SearcherManager, to manage sharing and reopening
IndexSearchers across multiple search threads. IndexReader's
refCount is used to safely close the reader only once all threads are done
using it. (Michael McCandless)
API Changes
* LUCENE-3431: Deprecated QueryAutoStopWordAnalyzer.addStopWords* since they
prevent reuse. Stopwords are now to be computed when the Analyzer is instantiated.
If new stopwords are needed, a new Analyzer instance should be created. (Chris Male)
* LUCENE-3434: Deprecated ShingleAnalyzerWrapper.set* since they prevent reuse. The
Analyzer should be configured at instantiation. Deprecated PerFieldAnalyzerWrapper.addAnalyzer
since it also prevents reuse. Analyzers per field should be configured at instantiation.
(Chris Male)
Bug Fixes
* LUCENE-3417: DictionaryCompoundWordFilter did not properly add tokens from the
end compound word. (Njal Karevoll via Robert Muir)
* LUCENE-3019: Fix unexpected color tags for FastVectorHighlighter. (Koji Sekiguchi)
* LUCENE-3446: Fix NPE in BooleanFilter when DocIdSet/DocIdSetIterator is null.
Converted code to FixedBitSet and simplified. (Uwe Schindler, Shuji Umino)
API Changes
* LUCENE-3436: Add SuggestMode to the spellchecker, so you can specify the strategy
for suggesting related terms. (James Dyer via Robert Muir)
======================= Lucene 3.4.0 ================
New Features
* LUCENE-3234: provide a limit on phrase analysis in FastVectorHighlighter for
highlighting speed up. Use FastVectorHighlighter.setPhraseLimit() to set limit
(e.g. 5000). (Mike Sokolov via Koji Sekiguchi)
* LUCENE-3079: a new facet module which provides faceted indexing & search
capabilities. It allows managing a taxonomy of categories, and index them
with documents. It also provides search API for aggregating (e.g. count)
the weights of the categories that are relevant to the search results.
(Shai Erera)
* LUCENE-3171: Added BlockJoinQuery and BlockJoinCollector, under the
new contrib/join module, to enable searches that require joining
between parent and child documents. Joined (children + parent)
documents must be indexed as a document block, using
IndexWriter.add/UpdateDocuments (Mark Harwood, Mike McCandless)
* LUCENE-3233, LUCENE-3375: Added SynonymFilter for applying multi-word synonyms
during indexing or querying (with parsers for wordnet and solr formats).
Removed contrib/wordnet. (Simon Rosenthal, Robert Muir, Mike McCandless)
* LUCENE-1768: added support for numeric ranges in contrib query parser;
added support for simple numeric queries, such as <age:4>, in contrib
query parser (Vinicius Barros via Uwe Schindler)
Changes in runtime behavior:
* LUCENE-1768: StandardQueryConfigHandler now uses NumericFieldConfigListener
to set a NumericConfig to its corresponding FieldConfig;
StandardQueryTreeBuilder now uses DummyQueryNodeBuilder for
NumericQueryNodes and uses NumericRangeQueryNodeBuilder for
NumericRangeQueryNodes; StandardQueryNodeProcessorPipeline now executes
NumericQueryNodeProcessor followed by NumericRangeQueryNodeProcessor
right after LowercaseExpandedTermsQueryNodeProcessor
(Vinicius Barros via Uwe Schindler)
API Changes
* LUCENE-3296: PKIndexSplitter & MultiPassIndexSplitter now have version
constructors. PKIndexSplitter accepts a IndexWriterConfig for each of
the target indexes. (Simon Willnauer, Jason Rutherglen)
* LUCENE-2979: queryparser configuration API located under
org.apache.lucene.queryParser.core.config has been simplified and
Attribute objects no longer should be used to configure query parsers. Now
any configuration should be done through AbstractQueryConfig's set and get
methods. The old API, which uses Attributes objects, is still in place, however
it has been deprecated and will be removed soon.
(Phillipe Ramalho via Adriano Crestani)
* LUCENE-3400: Deprecated DutchAnalyzer.setStemDictionary since it prevents
TokenStream reuse (Chris Male)
* LUCENE-1768: setNumericConfigMap and getNumericConfigMap were added
to StandardQueryParser; ParametricRangeQueryNode and
oal.queryParser.standard.nodes.RangeQueryNode now implement
oal.queryParser.core.nodes.RangeQueryNode;
oal.queryParser.core.nodes.RangeQueryNode was deprecated and now extends
TermRangeQueryNode, which extends AbstractRangeQueryNode;
ParametricQueryNode was deprecated; FieldQueryNode now implements the
new FieldValueQueryNode<CharSequence>, which this last one implements
FieldableQueryNode and thew new ValueQueryNode
(Vinicius Barros via Uwe Schindler)
Optimizations
* LUCENE-3306: Disabled indexing of positions for spellchecker n-gram
fields: they are not needed because the spellchecker does not
use positional queries. (Robert Muir)
Bug Fixes
* LUCENE-3326: Fixed bug if you used MoreLikeThis.like(Reader), it would
try to re-analyze the same Reader multiple times, passing different
field names to the analyzer. Additionally MoreLikeThisQuery would take
your string and encode/decode it using the default charset, it now uses
a StringReader. Finally, MoreLikeThis's methods that take File, URL, InputStream,
are deprecated, please create the Reader yourself. (Trejkaz, Robert Muir)
* LUCENE-3347: XML query parser did not always incorporate boosts from
UserQuery elements. (Moogie, Uwe Schindler)
* LUCENE-3382: Fixed a bug where NRTCachingDirectory's listAll() would wrongly
throw NoSuchDirectoryException when all files written so far have been
cached to RAM and the directory still has not yet been created on the
filesystem. (Robert Muir)
======================= Lucene 3.3.0 =======================
New Features
* LUCENE-152: Add KStem (light stemmer for English).
(Yonik Seeley via Robert Muir)
* LUCENE-3135: Add suggesters (autocomplete) to contrib/spellchecker,
with three implementations: Jaspell, Ternary Trie, and Finite State.
(Andrzej Bialecki, Dawid Weiss, Mike Mccandless, Robert Muir)
* LUCENE-3129: Added BlockGroupingCollector, a single pass
grouping collector which is faster than the two-pass approach, and
also computes the total group count, but requires that every
document sharing the same group was indexed as a doc block
(IndexWriter.add/updateDocuments). (Mike McCandless)
* LUCENE-2955: Added NRTManager and NRTManagerReopenThread, to
simplify handling NRT reopen with multiple search threads, and to
allow an app to control which indexing changes must be visible to
which search requests. (Mike McCandless)
* LUCENE-3191: Added SearchGroup.merge and TopGroups.merge, to
facilitate doing grouping in a distributed environment (Uwe
Schindler, Mike McCandless)
* LUCENE-2919: Added PKIndexSplitter, that splits an index according
to a middle term in a specified field. (Jason Rutherglen via Mike
McCandless, Uwe Schindler)
API Changes
* LUCENE-3141: add getter method to access fragInfos in FieldFragList.
(Sujit Pal via Koji Sekiguchi)
* LUCENE-3099: Allow subclasses to determine the group value for
First/SecondPassGroupingCollector. (Martijn van Groningen, Mike
McCandless)
Bug Fixes
* LUCENE-3185: Fix bug in NRTCachingDirectory.deleteFile that would
always throw exception and sometimes fail to actually delete the
file. (Mike McCandless)
* LUCENE-3188: contrib/misc IndexSplitter creates indexes with incorrect
SegmentInfos.counter; added CheckIndex check & fix for this problem.
(Ivan Dimitrov Vasilev via Steve Rowe)
Build
* LUCENE-3149: Upgrade contrib/icu's ICU jar file to ICU 4.8.
(Robert Muir)
======================= Lucene 3.2.0 =======================
Changes in backwards compatibility policy
* LUCENE-2981: Removed the following contribs: ant, db, lucli, swing. (Robert Muir)
Changes in runtime behavior
* LUCENE-3086: ItalianAnalyzer now uses ElisionFilter with a set of Italian
contractions by default. (Robert Muir)
Bug Fixes
* LUCENE-3045: fixed QueryNodeImpl.containsTag(String key) that was
not lowercasing the key before checking for the tag (Adriano Crestani)
* LUCENE-3026: SmartChineseAnalyzer's WordTokenFilter threw NullPointerException
on sentences longer than 32,767 characters. (wangzhenghang via Robert Muir)
* LUCENE-2939: Highlighter should try and use maxDocCharsToAnalyze in
WeightedSpanTermExtractor when adding a new field to MemoryIndex as well as
when using CachingTokenStream. This can be a significant performance bug for
large documents. (Mark Miller)
* LUCENE-3043: GermanStemmer threw IndexOutOfBoundsException if it encountered
a zero-length token. (Robert Muir)
* LUCENE-3044: ThaiWordFilter didn't reset its cached state correctly, this only
caused a problem if you consumed a tokenstream, then reused it, added different
attributes to it, and consumed it again. (Robert Muir, Uwe Schindler)
* LUCENE-3113: Fixed some minor analysis bugs: double-reset() in ReusableAnalyzerBase
and ShingleAnalyzerWrapper, missing end() implementations in PrefixAwareTokenFilter
and PrefixAndSuffixAwareTokenFilter, invocations of incrementToken() after it
already returned false in CommonGramsQueryFilter, HyphenatedWordsFilter,
ShingleFilter, and SynonymsFilter. (Robert Muir, Steven Rowe, Uwe Schindler)
New Features
* LUCENE-3016: Add analyzer for Latvian. (Robert Muir)
* LUCENE-1421: create new grouping contrib module, enabling search
results to be grouped by a single-valued indexed field. This
module was factored out of Solr's grouping implementation, but
it cannot group by function queries nor arbitrary queries. (Mike
McCandless)
* LUCENE-3098: add AllGroupsCollector, to collect all unique groups
(but in unspecified order). (Martijn van Groningen via Mike
McCandless)
* LUCENE-3092: Added NRTCachingDirectory in contrib/misc, which
caches small segments in RAM. This is useful, in the near-real-time
case where the indexing rate is lowish but the reopen rate is
highish, to take load off the IO system. (Mike McCandless)
Optimizations
* LUCENE-3040: Switch all analysis consumers (highlighter, morelikethis, memory, ...)
over to reusableTokenStream(). (Robert Muir)
======================= Lucene 3.1.0 =======================
Changes in backwards compatibility policy
* LUCENE-2100: All Analyzers in Lucene-contrib have been marked as final.
Analyzers should be only act as a composition of TokenStreams, users should
compose their own analyzers instead of subclassing existing ones.
(Simon Willnauer)
* LUCENE-2194, LUCENE-2201: Snowball APIs were upgraded to snowball revision
502 (with some local modifications for improved performance).
Index backwards compatibility and binary backwards compatibility is
preserved, but some protected/public member variables changed type. This
does NOT affect java code/class files produced by the snowball compiler,
but technically is a backwards compatibility break. (Robert Muir)
* LUCENE-2226: Moved contrib/snowball functionality into contrib/analyzers.
Be sure to remove any old obselete lucene-snowball jar files from your
classpath! (Robert Muir)
* LUCENE-2323: Moved contrib/wikipedia functionality into contrib/analyzers.
Additionally the package was changed from org.apache.lucene.wikipedia.analysis
to org.apache.lucene.analysis.wikipedia. (Robert Muir)
* LUCENE-2581: Added new methods to FragmentsBuilder interface. These methods
are used to set pre/post tags and Encoder. (Koji Sekiguchi)
* LUCENE-2391: Improved spellchecker (re)build time/ram usage by omitting
frequencies/positions/norms for single-valued fields, modifying the default
ramBufferMBSize to match IndexWriterConfig (16MB), making index optimization
an optional boolean parameter, and modifying the incremental update logic
to work well with unoptimized spellcheck indexes. The indexDictionary() methods
were made final to ensure a hard backwards break in case you were subclassing
Spellchecker. In general, subclassing Spellchecker is not recommended. (Robert Muir)
Changes in runtime behavior
* LUCENE-2117: SnowballAnalyzer uses TurkishLowerCaseFilter instead of
LowercaseFilter to correctly handle the unique Turkish casing behavior if
used with Version > 3.0 and the TurkishStemmer.
(Robert Muir via Simon Willnauer)
* LUCENE-2055: GermanAnalyzer now uses the Snowball German2 algorithm and
stopwords list by default for Version > 3.0.
(Robert Muir, Uwe Schindler, Simon Willnauer)
Bug fixes
* LUCENE-2855: contrib queryparser was using CharSequence as key in some internal
Map instances, which was leading to incorrect behavior, since some CharSequence
implementors do not override hashcode and equals methods. Now the internal Maps
are using String instead. (Adriano Crestani)
* LUCENE-2068: Fixed ReverseStringFilter which was not aware of supplementary
characters. During reverse the filter created unpaired surrogates, which
will be replaced by U+FFFD by the indexer, but not at query time. The filter
now reverses supplementary characters correctly if used with Version > 3.0.
(Simon Willnauer, Robert Muir)
* LUCENE-2035: TokenSources.getTokenStream() does not assign positionIncrement.
(Christopher Morris via Mark Miller)
* LUCENE-2055: Deprecated RussianTokenizer, RussianStemmer, RussianStemFilter,
FrenchStemmer, FrenchStemFilter, DutchStemmer, and DutchStemFilter. For
these Analyzers, SnowballFilter is used instead (for Version > 3.0), as
the previous code did not always implement the Snowball algorithm correctly.
Additionally, for Version > 3.0, the Snowball stopword lists are used by
default. (Robert Muir, Uwe Schindler, Simon Willnauer)
* LUCENE-2184: Fixed bug with handling best fit value when the proper best fit value is
not an indexed field. Note, this change affects the APIs. (Grant Ingersoll)
* LUCENE-2359: Fix bug in CartesianPolyFilterBuilder related to handling of behavior around
the 180th meridian (Grant Ingersoll)
* LUCENE-2404: Fix bugs with position increment and empty tokens in ThaiWordFilter.
For matchVersion >= 3.1 the filter also no longer lowercases. ThaiAnalyzer
will use a separate LowerCaseFilter instead. (Uwe Schindler, Robert Muir)
* LUCENE-2615: Fix DirectIOLinuxDirectory to not assign bogus
permissions to newly created files, and to not silently hardwire
buffer size to 1 MB. (Mark Miller, Robert Muir, Mike McCandless)
* LUCENE-2629: Fix gennorm2 task for generating ICUFoldingFilter's .nrm file. This allows
you to customize its normalization/folding, by editing the source data files in src/data
and regenerating a new .nrm with 'ant gennorm2'. (David Bowen via Robert Muir)
* LUCENE-2653: ThaiWordFilter depends on the JRE having a Thai dictionary, which is not
always the case. If the dictionary is unavailable, the filter will now throw
UnsupportedOperationException in the constructor. (Robert Muir)
* LUCENE-589: Fix contrib/demo for international documents.
(Curtis d'Entremont via Robert Muir)
* LUCENE-2246: Fix contrib/demo for Turkish html documents.
(Selim Nadi via Robert Muir)
* LUCENE-590: Demo HTML parser gives incorrect summaries when title is repeated as a heading
(Curtis d'Entremont via Robert Muir)
* LUCENE-591: The demo indexer now indexes meta keywords.
(Curtis d'Entremont via Robert Muir)
* LUCENE-2874: Highlighting overlapping tokens outputted doubled words.
(Pierre Gossé via Robert Muir)
* LUCENE-2943: Fix thread-safety issues with ICUCollationKeyFilter.
(Robert Muir)
* LUCENE-3087: Highlighter: fix case that was preventing highlighting
of exact phrase when tokens overlap. (Pierre Gossé via Mike
McCandless)
API Changes
* LUCENE-2867: Some contrib queryparser methods that receives CharSequence as
identifier, such as QueryNode#unsetTag(CharSequence), were deprecated and
will be removed on version 4. (Adriano Crestani)
* LUCENE-2147: Spatial GeoHashUtils now always decode GeoHash strings
with full precision. GeoHash#decode_exactly(String) was merged into
GeoHash#decode(String). (Chris Male, Simon Willnauer)
* LUCENE-2204: Change some package private classes/members to publicly accessible to implement
custom FragmentsBuilders. (Koji Sekiguchi)
* LUCENE-2055: Integrate snowball into contrib/analyzers. SnowballAnalyzer is
now deprecated in favor of language-specific analyzers which contain things
such as stopword lists and any language-specific processing in addition to
stemming. Add Turkish and Romanian stopwords lists to support this.
(Robert Muir, Uwe Schindler, Simon Willnauer)
* LUCENE-2603: Add setMultiValuedSeparator(char) method to set an arbitrary
char that is used when concatenating multiValued data. Default is a space
(' '). It is applied on ANALYZED field only. (Koji Sekiguchi)
* LUCENE-2626: FastVectorHighlighter: enable FragListBuilder and FragmentsBuilder
to be set per-field override. (Koji Sekiguchi)
* LUCENE-2712: FieldBoostMapAttribute in contrib/queryparser was changed from
a Map<CharSequence,Float> to a Map<String,Float>. Per the CharSequence javadoc,
CharSequence is inappropriate as a map key. (Robert Muir)
* LUCENE-1937: Add more methods to manipulate QueryNodeProcessorPipeline elements.
QueryNodeProcessorPipeline now implements the List interface, this is useful
if you want to extend or modify an existing pipeline. (Adriano Crestani via Robert Muir)
* LUCENE-2754, LUCENE-2757: Deprecated SpanRegexQuery. Use
new SpanMultiTermQueryWrapper<RegexQuery>(new RegexQuery()) instead.
(Robert Muir, Uwe Schindler)
* LUCENE-2747: Deprecated ArabicLetterTokenizer. StandardTokenizer now tokenizes
most languages correctly including Arabic. (Steven Rowe, Robert Muir)
* LUCENE-2830: Use StringBuilder instead of StringBuffer across Benchmark, and
remove the StringBuffer HtmlParser.parse() variant. (Shai Erera)
* LUCENE-2920: Deprecated ShingleMatrixFilter as it is unmaintained and does
not work with custom Attributes or custom payload encoders. (Uwe Schindler)
New features
* LUCENE-2500: Added DirectIOLinuxDirectory, a Linux-specific
Directory impl that uses the O_DIRECT flag to bypass the buffer
cache. This is useful to prevent segment merging from evicting
pages from the buffer cache, since fadvise/madvise do not seem.
(Michael McCandless)
* LUCENE-2306: Add NumericRangeFilter and NumericRangeQuery support to XMLQueryParser.
(Jingkei Ly, via Mark Harwood)
* LUCENE-2102: Add a Turkish LowerCase Filter. TurkishLowerCaseFilter handles
Turkish and Azeri unique casing behavior correctly.
(Ahmet Arslan, Robert Muir via Simon Willnauer)
* LUCENE-2039: Add a extensible query parser to contrib/misc.
ExtendableQueryParser enables arbitrary parser extensions based on a
customizable field naming scheme.
(Simon Willnauer)
* LUCENE-2067: Add a Czech light stemmer. CzechAnalyzer will now stem words
when Version is set to 3.1 or higher. (Robert Muir)
* LUCENE-2062: Add a Bulgarian analyzer. (Robert Muir, Simon Willnauer)
* LUCENE-2206: Add Snowball's stopword lists for Danish, Dutch, English,
Finnish, French, German, Hungarian, Italian, Norwegian, Russian, Spanish,
and Swedish. These can be loaded with WordListLoader.getSnowballWordSet.
(Robert Muir, Simon Willnauer)
* LUCENE-2243: Add DisjunctionMaxQuery support for FastVectorHighlighter.
(Koji Sekiguchi)
* LUCENE-2218: ShingleFilter supports minimum shingle size, and the separator
character is now configurable. Its also up to 20% faster.
(Steven Rowe via Robert Muir)
* LUCENE-2234: Add a Hindi analyzer. (Robert Muir)
* LUCENE-2055: Add analyzers/misc/StemmerOverrideFilter. This filter provides
the ability to override any stemmer with a custom dictionary map.
(Robert Muir, Uwe Schindler, Simon Willnauer)
* LUCENE-2399: Add ICUNormalizer2Filter, which normalizes tokens with ICU's
Normalizer2. This allows for efficient combinations of normalization and custom
mappings in addition to standard normalization, and normalization combined
with unicode case folding. (Robert Muir)
* LUCENE-1343: Add ICUFoldingFilter, a replacement for ASCIIFoldingFilter that
does a more thorough job of normalizing unicode text for search.
(Robert Haschart, Robert Muir)
* LUCENE-2409: Add ICUTransformFilter, which transforms text in a context
sensitive way, either from ICU built-in rules (such as Traditional-Simplified),
or from rules you write yourself. (Robert Muir)
* LUCENE-2414: Add ICUTokenizer, a tailorable tokenizer that implements Unicode
Text Segmentation. This tokenizer is useful for documents or collections with
multiple languages. The default configuration includes special support for
Thai, Lao, Myanmar, and Khmer. (Robert Muir, Uwe Schindler)
* LUCENE-2298: Add analyzers/stempel, an algorithmic stemmer with support for
the Polish language. (Andrzej Bialecki via Robert Muir)
* LUCENE-2400: ShingleFilter was changed to don't output all-filler shingles and
unigrams, and uses a more performant algorithm to build grams using a linked list
of AttributeSource.cloneAttributes() instances and the new copyTo() method.
(Steven Rowe via Uwe Schindler)
* LUCENE-2437: Add an Analyzer for Indonesian. (Robert Muir)
* LUCENE-2393: The HighFreqTerms tool (in misc) can now optionally
also include the total termFreq. (Tom Burton-West via Mike McCandless)
* LUCENE-2463: Add a Greek inflectional stemmer. GreekAnalyzer will now stem words
when Version is set to 3.1 or higher. (Robert Muir)
* LUCENE-1287: Allow usage of HyphenationCompoundWordTokenFilter without dictionary.
(Thomas Peuss via Robert Muir)
* LUCENE-2464: FastVectorHighlighter: add SingleFragListBuilder to return
entire field contents. (Koji Sekiguchi)
* LUCENE-2503: Added lighter stemming alternatives for European languages.
(Robert Muir)
* LUCENE-2581: FastVectorHighlighter: add Encoder to FragmentsBuilder.
(Koji Sekiguchi)
* LUCENE-2624: Add Analyzers for Armenian, Basque, and Catalan, from snowball.
(Robert Muir)
* LUCENE-1938: PrecedenceQueryParser is now implemented with the flexible QP framework.
This means that you can also add this functionality to your own QP pipeline by using
BooleanModifiersQueryNodeProcessor, for example instead of GroupQueryNodeProcessor.
(Adriano Crestani via Robert Muir)
* LUCENE-2791: Added WindowsDirectory, a Windows-specific Directory impl
that doesn't synchronize on the file handle. This can be useful to
avoid the performance problems of SimpleFSDirectory and NIOFSDirectory.
(Robert Muir, Simon Willnauer, Uwe Schindler, Michael McCandless)
* LUCENE-2842: Add analyzer for Galician. Also adds the RSLP (Orengo) stemmer
for Portuguese. (Robert Muir)
* SOLR-1057: Add PathHierarchyTokenizer that represents file path hierarchies as synonyms of
/something, /something/something, /something/something/else. (Ryan McKinley, Koji Sekiguchi)
Build
* LUCENE-2124: Moved the JDK-based collation support from contrib/collation
into core, and moved the ICU-based collation support into contrib/icu.
(Steven Rowe, Robert Muir)
* LUCENE-2323: Moved contrib/regex into contrib/queries. Moved the
queryparsers under contrib/misc and contrib/surround into contrib/queryparser.
Moved contrib/fast-vector-highlighter into contrib/highlighter.
Moved ChainedFilter from contrib/misc to contrib/queries. contrib/spatial now
depends on contrib/queries instead of contrib/misc. (Robert Muir)
* LUCENE-2333: Fix failures during contrib builds, when classes in
core were changed without ant clean. This fix also optimizes the
dependency management between contribs by a new ANT macro.
(Uwe Schindler, Shai Erera)
* LUCENE-2797: Upgrade contrib/icu's ICU jar file to ICU 4.6
(Robert Muir)
* LUCENE-2833: Upgrade contrib/ant's jtidy jar file to r938 (Robert Muir)
* LUCENE-2413: Moved the demo out of lucene core and into contrib/demo.
(Robert Muir)
Optimizations
* LUCENE-2157: DelimitedPayloadTokenFilter no longer copies the buffer
over itsself. Instead it sets only the length. This patch also optimizes
the logic of the filter and uses NIO for IdentityEncoder. (Uwe Schindler)
* LUCENE-2084: Change IndexableBinaryStringTools to work on byte[] and char[]
directly, instead of Byte/CharBuffers, and modify ICUCollationKeyFilter to
take advantage of this for faster performance.
(Steven Rowe, Uwe Schindler, Robert Muir)
* LUCENE-2194, LUCENE-2201, LUCENE-2288: Snowball stemmers in contrib/analyzers
have been optimized to work on char[] and remove unnecessary object creation.
(Shai Erera, Robert Muir)
* LUCENE-2404: Improve performance of ThaiWordFilter by using a char[]-backed
CharacterIterator (currently from javax.swing). (Uwe Schindler, Robert Muir)
Test Cases
* LUCENE-2115: Cutover contrib tests to use Java5 generics. (Kay Kay
via Mike McCandless)
Other
* LUCENE-1845: Updated bdb-je jar from version 3.3.69 to 3.3.93.
(Simon Willnauer via Mike McCandless)
* LUCENE-2415: Use reflection instead of a shim class to access Jakarta
Regex prefix. (Uwe Schindler)
================== Release 2.9.4 / 3.0.3 ====================
Bug Fixes
* LUCENE-2277: QueryNodeImpl threw ConcurrentModificationException on
add(List<QueryNode>). (Frank Wesemann via Robert Muir)
* LUCENE-2284: MatchAllDocsQueryNode toString() created an invalid XML tag.
(Frank Wesemann via Robert Muir)
* LUCENE-2278: FastVectorHighlighter: Highlighted term is out of alignment
in multi-valued NOT_ANALYZED field. (Koji Sekiguchi)
* LUCENE-2524: FastVectorHighlighter: use mod for getting colored tag.
(Koji Sekiguchi)
* LUCENE-2616: FastVectorHighlighter: out of alignment when the first value is
empty in multiValued field (Koji Sekiguchi)
* LUCENE-2731, LUCENE-2732: Fix (charset) problems in XML loading in
HyphenationCompoundWordTokenFilter (partial bugfix-only in 2.9 and 3.0,
full fix will be in later 3.1).
(Uwe Schinder)
Documentation
* LUCENE-2055: Add documentation noting that the Dutch and French stemmers
in contrib/analyzers do not implement the Snowball algorithm correctly,
and recommend to use the equivalents in contrib/snowball if possible.
(Robert Muir, Uwe Schindler, Simon Willnauer)
* LUCENE-2653: Add documentation noting that ThaiWordFilter will not work
as expected on all JRE's. For example, on an IBM JRE, it does nothing.
(Robert Muir)
================== Release 2.9.3 / 3.0.2 ====================
No changes.
================== Release 2.9.2 / 3.0.1 ====================
New features
* LUCENE-2108: Spellchecker now safely supports concurrent modifications to
the spell-index. Threads can safely obtain term suggestions while the spell-
index is rebuild, cleared or reset. Internal IndexSearcher instances remain
open until the last thread accessing them releases the reference.
(Simon Willnauer)
Bug Fixes
* LUCENE-2144: Fix InstantiatedIndex to handle termDocs(null)
correctly (enumerate all non-deleted docs). (Karl Wettin via Mike
McCandless)
* LUCENE-2199: ShingleFilter skipped over tri-gram shingles if outputUnigram
was set to false. (Simon Willnauer)
* LUCENE-2211: Fix missing clearAttributes() calls:
ShingleMatrix, PrefixAware, compounds, NGramTokenFilter,
EdgeNGramTokenFilter, Highlighter, and MemoryIndex.
(Uwe Schindler, Robert Muir)
* LUCENE-2207, LUCENE-2219: Fix incorrect offset calculations in end() for
CJKTokenizer, ChineseTokenizer, SmartChinese SentenceTokenizer,
and WikipediaTokenizer. (Koji Sekiguchi, Robert Muir)
* LUCENE-2266: Fixed offset calculations in NGramTokenFilter and
EdgeNGramTokenFilter. (Joe Calderon, Robert Muir via Uwe Schindler)
API Changes
* LUCENE-2108: Add SpellChecker.close, to close the underlying
reader. (Eirik Bjørsnøs via Mike McCandless)
* LUCENE-2165: Add a constructor to SnowballAnalyzer that takes a Set of
stopwords, and deprecate the String[] one. (Nick Burch via Robert Muir)
======================= Release 3.0.0 =======================
Changes in backwards compatibility policy
* LUCENE-1257: Change some occurences of StringBuffer in public/protected
APIs of contrib/surround to StringBuilder.
(Paul Elschot via Uwe Schindler)
Changes in runtime behavior
* LUCENE-1966: Modified and cleaned the default Arabic stopwords list used
by ArabicAnalyzer. You'll need to fully re-index any previously created
indexes. (Basem Narmok via Robert Muir)
API Changes
* LUCENE-1936: Deprecated RussianLowerCaseFilter, because it transforms
text exactly the same as LowerCaseFilter. Please use LowerCaseFilter
instead, which has the same functionality. (Robert Muir)
* LUCENE-2051: Contrib Analyzer setters were deprecated and replaced
with ctor arguments / Version number. Also stop word lists
were unified. (Simon Willnauer)
Bug fixes
* LUCENE-1781: Fixed various issues with the lat/lng bounding box
distance filter created for radius search in contrib/spatial.
(Bill Bell via Mike McCandless)
* LUCENE-1939: IndexOutOfBoundsException at ShingleMatrixFilter's
Iterator#hasNext method on exhausted streams.
(Patrick Jungermann via Karl Wettin)
* LUCENE-1359: French analyzer did not support null field names.
(Andrew Lynch via Robert Muir)
New features
* LUCENE-1924: Added BalancedSegmentMergePolicy to contrib/misc,
which is a merge policy that tries to avoid doing very large
segment merges to give better search performance in a mixed
indexing/searching environment. (John Wang via Mike McCandless)
* LUCENE-1959: Add index splitting tools. The IndexSplitter tool works
on multi-segment (non optimized) indexes and it can copy specific
segments out of the index into a new index. It can also list the
segments in the index, and delete specified segments. (Jason Rutherglen via
Mike McCandless). MultiPassIndexSplitter can split any index into
any number of output parts, at the cost of doing multiple passes over
the input index. (Andrzej Bialecki)
* LUCENE-1993: Add maxDocFreq setting to MoreLikeThis, to exclude
from consideration terms that match more than the specified number
of documents. (Christian Steinert via Mike McCandless)
Optimizations
* LUCENE-1965, LUCENE-1962: Arabic-, Persian- and SmartChineseAnalyzer
loads default stopwords only once if accessed for the first time.
Previous versions were loading the stopword files each time a new
instance was created. This might improve performance for applications
creating lots of instances of these Analyzers. (Simon Willnauer)
Documentation
* LUCENE-1916: Translated documentation in the smartcn hhmm package.
(Patricia Peng via Robert Muir)
Build
* LUCENE-1904: Moved wordnet-based synonym support from contrib/memory
into contrib/wordnet. (Robert Muir)
* LUCENE-2031: Moved PatternAnalyzer from contrib/memory into
contrib/analyzers/common, under miscellaneous. (Robert Muir)
======================= Release 2.9.1 =======================
Changes in backwards compatibility policy
* LUCENE-2002: Add required Version matchVersion argument when
constructing ComplexPhraseQueryParser and default (as of 2.9)
enablePositionIncrements to true to match StandardAnalyzer's
default. Also added required matchVersion to most of the analyzers
(Uwe Schindler, Mike McCandless)
Changes in runtime behavior
* LUCENE-1963: ArabicAnalyzer now lowercases before checking the stopword
list. This has no effect on Arabic text, but if you are using a custom
stopword list that contains some non-Arabic words, you'll need to fully
reindex. (DM Smith via Robert Muir)
Bug fixes
* LUCENE-1953: FastVectorHighlighter: small fragCharSize can cause
StringIndexOutOfBoundsException. (Koji Sekiguchi)
* LUCENE-1929: Highlighter throws exception on NumericRangeQuery and does not
support deprecated RangeQuery. (Mark Miller)
* LUCENE-2001: Wordnet Syns2Index incorrectly parses synonyms that
contain a single quote. (Parag H. Dave via Robert Muir)
* LUCENE-2003: Highlighter doesn't respect position increments other than 1 with
PhraseQuerys. (Uwe Schindler, Mark Miller)
* LUCENE-1954: InstantiatedIndexWriter: Fixed ClassCastException with
NumericField because of incorrect unchecked cast: Document.getFields()
returns List<Fieldable>. (Bernd Fondermann via Uwe Schindler)
* LUCENE-2014: SmartChineseAnalyzer did not properly clear attributes
in WordTokenFilter. If enablePositionIncrements is set for StopFilter,
then this could create invalid position increments, causing IndexWriter
to crash. (Robert Muir, Uwe Schindler)
* LUCENE-2013: SpanRegexQuery does not work with QueryScorer.
(Benjamin Keil via Mark Miller)
======================= Release 2.9.0 =======================
Changes in runtime behavior
* LUCENE-1505: Local lucene now uses org.apache.lucene.util.NumericUtils for all
number conversion. You'll need to fully re-index any previously created indexes.
This isn't a break in back-compatibility because local Lucene has not yet
been released. (Mike McCandless)
* LUCENE-1758: ArabicAnalyzer now uses the light10 algorithm, has a refined
default stopword list, and lowercases non-Arabic text.
You'll need to fully re-index any previously created indexes. This isn't a
break in back-compatibility because ArabicAnalyzer has not yet been
released. (Robert Muir)
API Changes
* LUCENE-1695: Update the Highlighter to use the new TokenStream API. This issue breaks backwards
compatibility with some public classes. If you have implemented custom Fragmenters or Scorers,
you will need to adjust them to work with the new TokenStream API. Rather than getting passed a
Token at a time, you will be given a TokenStream to init your impl with - store the Attributes
you are interested in locally and access them on each call to the method that used to pass a new
Token. Look at the included updated impls for examples. (Mark Miller)
* LUCENE-1460: Change contrib TokenStreams/Filters to use the new
TokenStream API. (Robert Muir, Michael Busch)
* LUCENE-1775, LUCENE-1903: Change remaining TokenFilters (shingle, prefix-suffix)
to use the new TokenStream API. ShingleFilter is much more efficient now,
it clones much less often and computes the tokens mostly on the fly now.
Also added more tests. (Robert Muir, Michael Busch, Uwe Schindler, Chris Harris)
* LUCENE-1685: The position aware SpanScorer has become the default scorer
for Highlighting. The SpanScorer implementation has replaced QueryScorer
and the old term highlighting QueryScorer has been renamed to
QueryTermScorer. Multi-term queries are also now expanded by default. If
you were previously rewriting the query for multi-term query highlighting,
you should no longer do that (unless you switch to using QueryTermScorer).
The SpanScorer API (now QueryScorer) has also been improved to more closely
match the API of the previous QueryScorer implementation. (Mark Miller)
* LUCENE-1793: Deprecate the custom encoding support in the Greek and Russian
Analyzers. If you need to index text in these encodings, please use Java's
character set conversion facilities (InputStreamReader, etc) during I/O,
so that Lucene can analyze this text as Unicode instead. (Robert Muir)
Bug fixes
* LUCENE-1423: InstantiatedTermEnum#skipTo(Term) throws ArrayIndexOutOfBounds on empty index.
(Karl Wettin)
* LUCENE-1462: InstantiatedIndexWriter did not reset pre analyzed TokenStreams the
same way IndexWriter does. Parts of InstantiatedIndex was not Serializable.
(Karl Wettin)
* LUCENE-1510: InstantiatedIndexReader#norms methods throws NullPointerException on empty index.
(Karl Wettin, Robert Newson)
* LUCENE-1514: ShingleMatrixFilter#next(Token) easily throws a StackOverflowException
due to recursive invocation. (Karl Wettin)
* LUCENE-1548: Fix distance normalization in LevenshteinDistance to
not produce negative distances (Thomas Morton via Mike McCandless)
* LUCENE-1490: Fix latin1 conversion of HALFWIDTH_AND_FULLWIDTH_FORMS
characters to only apply to the correct subset (Daniel Cheng via
Mike McCandless)
* LUCENE-1576: Fix BrazilianAnalyzer to downcase tokens after
StandardTokenizer so that stop words with mixed case are filtered
out. (Rafael Cunha de Almeida, Douglas Campos via Mike McCandless)
* LUCENE-1491: EdgeNGramTokenFilter no longer stops on tokens shorter than minimum n-gram size.
(Todd Teak via Otis Gospodnetic)
* LUCENE-1683: Fixed JavaUtilRegexCapabilities (an impl used by
RegexQuery) to use Matcher.matches() not Matcher.lookingAt() so
that the regexp must match the entire string, not just a prefix.
(Trejkaz via Mike McCandless)
* LUCENE-1792: Fix new query parser to set rewrite method for
multi-term queries. (Luis Alves, Mike McCandless via Michael Busch)
* LUCENE-1828: Fix memory index to call TokenStream.reset() and
TokenStream.end(). (Tim Smith via Michael Busch)
* LUCENE-1912: Fix fast-vector-highlighter issue when two or more
terms are concatenated (Koji Sekiguchi via Mike McCandless)
New features
* LUCENE-1531: Added support for BoostingTermQuery to XML query parser. (Karl Wettin)
* LUCENE-1435: Added contrib/collation, a CollationKeyFilter
allowing you to convert tokens into CollationKeys encoded using
IndexableBinaryStringTools. This allows for faster RangeQuery when
a field needs to use a custom Collator. (Steven Rowe via Mike
McCandless)
* LUCENE-1591: EnWikiDocMaker, LineDocMaker, WriteLineDoc can now
read/write bz2 using Apache commons compress library. This means
you can download the .bz2 export from http://wikipedia.org and
immediately index it. (Shai Erera via Mike McCandless)
* LUCENE-1629: Add SmartChineseAnalyzer to contrib/analyzers. It
improves on CJKAnalyzer and ChineseAnalyzer by handling Chinese
sentences properly. SmartChineseAnalyzer uses a Hidden Markov
Model to tokenize Chinese words in a more intelligent way.
(Xiaoping Gao via Mike McCandless)
* LUCENE-1676: Added DelimitedPayloadTokenFilter class for automatically adding payloads "in-stream" (Grant Ingersoll)
* LUCENE-1578: Support for loading unoptimized readers to the
constructor of InstantiatedIndex. (Karl Wettin)
* LUCENE-1704: Allow specifying the Tidy configuration file when
parsing HTML docs with contrib/ant. (Keith Sprochi via Mike
McCandless)
* LUCENE-1522: Added contrib/fast-vector-highlighter, a new alternative
highlighter. (Koji Sekiguchi via Mike McCandless)
* LUCENE-1740: Added "analyzer" command to Lucli, enabling changing
the analyzer from the default StandardAnalyzer. (Bernd Fondermann
via Mike McCandless)
* LUCENE-1272: Add get/setBoost to MoreLikeThis. (Jonathan
Leibiusky via Mike McCandless)
* LUCENE-1745: Added constructors to JakartaRegexpCapabilities and
JavaUtilRegexCapabilities as well as static flags to support
configuring a RegexCapabilities implementation with the
implementation-specific modifier flags. Allows for callers to
customize the RegexQuery using the implementation-specific options
and fine tune how regular expressions are compiled and
matched. (Marc Zampetti zampettim@aim.com via Mike McCandless)
* LUCENE-1567: Added a new QueryParser framework, that allows
implementing a new query syntax in a flexible and efficient way.
This new QueryParser will be moved to Lucene's core in release
3.0 and will then replace the current core QueryParser, which
has been deprecated with this patch.
(Luis Alves and Adriano Campos via Michael Busch)
* LUCENE-1486: Added ComplexPhraseQueryParser, an extension of QueryParser
that allows a subset of the Lucene query language to be embedded in
PhraseQuerys. Wildcard, Range, and Fuzzy queries, as well as limited
boolean logic, can be used within quote operators with this parser, ie:
"(jo* -john) smyth~". (Mark Harwood via Mark Miller)
* Added web-based demo of functionality in contrib's XML Query Parser
packaged as War file (Mark Harwood)
* LUCENE-1406: Added Arabic analyzer. (Robert Muir via Grant Ingersoll)
* LUCENE-1628: Added Persian analyzer. (Robert Muir)
* LUCENE-1813: Add option to ReverseStringFilter to mark reversed tokens.
(Andrzej Bialecki via Robert Muir)
Optimizations
* LUCENE-1643: Re-use the collation key (RawCollationKey) for
better performance, in ICUCollationKeyFilter. (Robert Muir via
Mike McCandless)
* LUCENE-1794: Implement TokenStream reuse for contrib Analyzers,
and implement reset() for TokenStreams to support reuse. (Robert Muir)
Documentation
* LUCENE-1876: added missing package level documentation for numerous
contrib packages.
(Steven Rowe & Robert Muir)
Build
* LUCENE-1728: Split contrib/analyzers into common and smartcn modules.
Contrib/analyzers now builds an additional lucene-smartcn Jar file. All
smartcn classes are not included in the lucene-analyzers JAR file.
(Robert Muir via Simon Willnauer)
* LUCENE-1829: Fix contrib query parser to properly create javacc files.
(Jan-Pascal and Luis Alves via Michael Busch)
