| <!-- The CodecFactory for defining the format of the inverted index. |
| The default implementation is SchemaCodecFactory, which is the official Lucene |

| the postings lists and per-document values in the fieldType element |
| (postingsFormat/docValuesFormat). Note that most of the alternative implementations |
| are experimental, so if you choose to customize the index format, it's a good |

| |
| There are two implementations of cache available for Solr, |

| FastLRUCache, based on a ConcurrentHashMap. |
| |
| FastLRUCache has faster gets and slower puts in single |
| threaded operation and thus is generally faster than LRUCache |
| when the hit ratio of the cache is high (> 75%), and may be |
| faster under other scenarios on multi-cpu systems. |

| <!-- Filter Cache |
| |
| Cache used by SolrIndexSearcher for filters (DocSets), |
| unordered sets of *all* documents that match a query. When a |

| autowarmCount is the number of items to prepopulate. For |
| LRUCache, the autowarmed items will be the most recently |
| accessed items. |
| |
| Parameters: |
| class - the SolrCache implementation LRUCache or |
| (LRUCache or FastLRUCache) |
| size - the maximum number of entries in the cache |
| initialSize - the initial capacity (number of entries) of |

| <!-- Request Dispatcher |
| |
| This section contains instructions for how the SolrDispatchFilter |
| should behave when processing requests for this SolrCore. |
| |
| handleSelect is a legacy option that affects the behavior of requests |
| such as /select?qt=XXX |
| |
| handleSelect="true" will cause the SolrDispatchFilter to process |
| the request and dispatch the query to a handler specified by the |
| "qt" param, assuming "/select" isn't already registered. |
| |
| handleSelect="false" will cause the SolrDispatchFilter to |
| ignore "/select" requests, resulting in a 404 unless a handler |
| is explicitly registered with the name "/select" |
| |
| handleSelect="true" is not recommended for new users, but is the default |
| for backwards compatibility |
| --> |
| <requestDispatcher handleSelect="false" > |
| <!-- Request Parsing |
| |
| These settings indicate how Solr Requests may be parsed, and |
| what restrictions may be placed on the ContentStreams from |
| those requests |
| |
| enableRemoteStreaming - enables use of the stream.file |
| and stream.url parameters for specifying remote streams. |
| |
| multipartUploadLimitInKB - specifies the max size (in KiB) of |
| Multipart File Uploads that Solr will allow in a Request. |
| |
| formdataUploadLimitInKB - specifies the max size (in KiB) of |
| form data (application/x-www-form-urlencoded) sent via |
| POST. You can use POST to pass request parameters not |
| fitting into the URL. |
| |
| addHttpRequestToContext - if set to true, it will instruct |
| the requestParsers to include the original HttpServletRequest |
| object in the context map of the SolrQueryRequest under the |
| key "httpRequest". It will not be used by any of the existing |
| Solr components, but may be useful when developing custom |
| plugins. |
| |
| *** WARNING *** |
| The settings below authorize Solr to fetch remote files, You |
| should make sure your system has some authentication before |
| using enableRemoteStreaming="true" |

| <!-- Request Handlers |
| |
| http://wiki.apache.org/solr/SolrRequestHandler |
| |
| Incoming queries will be dispatched to a specific handler by name |
| based on the path specified in the request. |
| |
| Legacy behavior: If the request path uses "/select" but no Request |
| Handler has that name, and if handleSelect="true" has been specified in |
| the requestDispatcher, then the Request Handler is dispatched based on |
| the qt parameter. Handlers without a leading '/' are accessed this way |
| like so: http://host/app/[core/]select?qt=name If no qt is |
| given, then the requestHandler that declares default="true" will be |
| used or the one named "standard". |

| If a Request Handler is declared with startup="lazy", then it will |

| |
| An analysis handler that provides a breakdown of the analysis |

| Note: Each document must contain a field which serves as the |
| unique key. This key is used in the returned response to associate |
| an analysis breakdown to the analyzed document. |
| |
| Like the FieldAnalysisRequestHandler, this handler also supports |
| query analysis by sending either an "analysis.query" or "q" |
| request parameter that holds the query text to be analyzed. It |
| also supports the "analysis.showmatch" parameter which when set to |
| true, all field tokens that match the query tokens will be marked |
