| </h1> |
| <div class="markdown level0 summary"><p>Tokenizes the input into n-grams of the given size(s). |
| <p>On the contrary to <a class="xref" href="Lucene.Net.Analysis.NGram.NGramTokenFilter.html">NGramTokenFilter</a>, this class sets offsets so |
| that characters between startOffset and endOffset in the original stream are |
| the same as the term chars. |
| </p> |
| <p>For example, "abcde" would be tokenized as (minGram=2, maxGram=3): |
| <table><thead><tr><th>TermPosition incrementPosition lengthOffsets</th><th></th></tr></thead><tbody><tr><td>ab11[0,2[</td><td></td></tr><tr><td>abc11[0,3[</td><td></td></tr><tr><td>bc11[1,3[</td><td></td></tr><tr><td>bcd11[1,4[</td><td></td></tr><tr><td>cd11[2,4[</td><td></td></tr><tr><td>cde11[2,5[</td><td></td></tr><tr><td>de11[3,5[</td><td></td></tr></tbody></table> |
| </p> |
| <p>This tokenizer changed a lot in Lucene 4.4 in order to: |
| <ul><li>tokenize in a streaming fashion to support streams which are larger |
| than 1024 chars (limit of the previous version),</li><li>count grams based on unicode code points instead of java chars (and |
| never split in the middle of surrogate pairs),</li><li>give the ability to pre-tokenize the stream (<a class="xref" href="Lucene.Net.Analysis.NGram.NGramTokenizer.html#Lucene_Net_Analysis_NGram_NGramTokenizer_IsTokenChar_System_Int32_">IsTokenChar(Int32)</a>) |
| before computing n-grams.</li></ul> |
| </p> |
| <p>Additionally, this class doesn't trim trailing whitespaces and emits |
| tokens in a different order, tokens are now emitted by increasing start |
| offsets while they used to be emitted by increasing lengths (which prevented |
| from supporting large input streams). |
| </p> |
| <p>Although <strong>highly</strong> discouraged, it is still possible |
| to use the old behavior through <a class="xref" href="Lucene.Net.Analysis.NGram.Lucene43NGramTokenizer.html">Lucene43NGramTokenizer</a>. |
