149 <!-- Expert: Merge Policy
150 The Merge Policy in Lucene controls how merging of segments is done.
151 The default since Solr/Lucene 3.3 is TieredMergePolicy.
152 The default since Lucene 2.3 was the LogByteSizeMergePolicy,
153 Even older versions of Lucene used LogDocMergePolicy.
156 <mergePolicy class="org.apache.lucene.index.TieredMergePolicy">
157 <int name="maxMergeAtOnce">10</int>
158 <int name="segmentsPerTier">10</int>
163 The merge factor controls how many segments will get merged at a time.
164 For TieredMergePolicy, mergeFactor is a convenience parameter which
165 will set both MaxMergeAtOnce and SegmentsPerTier at once.
166 For LogByteSizeMergePolicy, mergeFactor decides how many new segments
167 will be allowed before they are merged into one.
168 Default is 10 for both merge policies.
171 <mergeFactor>10</mergeFactor>
174 <!-- Expert: Merge Scheduler
175 The Merge Scheduler in Lucene controls how merges are
176 performed. The ConcurrentMergeScheduler (Lucene 2.3 default)
177 can perform merges in the background using separate threads.
178 The SerialMergeScheduler (Lucene 2.2 default) does not.
181 <mergeScheduler class="org.apache.lucene.index.ConcurrentMergeScheduler"/>
186 This option specifies which Lucene LockFactory implementation
189 single = SingleInstanceLockFactory - suggested for a
190 read-only index or when there is no possibility of
191 another process trying to modify the index.
192 native = NativeFSLockFactory - uses OS native file locking.
193 Do not use when multiple solr webapps in the same
194 JVM are attempting to share a single index.
195 simple = SimpleFSLockFactory - uses a plain file for locking
197 Defaults: 'native' is default for Solr3.6 and later, otherwise
198 'simple' is the default

203 <!-- <lockType>native</lockType> -->
205 <!-- Unlock On Startup
207 If true, unlock any held write or commit locks on startup.
208 This defeats the locking mechanism that allows multiple
209 processes to safely access a lucene index, and should be used
210 with care. Default is "false".
212 This is not needed if lock type is 'none' or 'single'
215 <unlockOnStartup>false</unlockOnStartup>
218 <!-- Expert: Controls how often Lucene loads terms into memory
219 Default is 128 and is likely good for most everyone.

224 instead of closed and then opened. Default: true

230 <!-- Commit Deletion Policy
232 Custom deletion policies can be specified here. The class must
233 implement org.apache.lucene.index.IndexDeletionPolicy.
235 http://lucene.apache.org/java/3_5_0/api/core/org/apache/lucene/index/IndexDeletionPolicy.html
237 The default Solr IndexDeletionPolicy implementation supports
238 deleting index commit points on number of commits, age of
239 commit point and optimized status.
241 The latest commit point should always be preserved regardless
245 <deletionPolicy class="solr.SolrDeletionPolicy">
247 <!-- The number of commit points to be kept -->
248 <!-- <str name="maxCommitsToKeep">1</str> -->
249 <!-- The number of optimized commit points to be kept -->
250 <!-- <str name="maxOptimizedCommitsToKeep">0</str> -->
252 Delete all commit points once they have reached the given age.
253 Supports DateMathParser syntax e.g.
256 <str name="maxCommitAge">30MINUTES</str>
257 <str name="maxCommitAge">1DAY</str>
263 <!-- Lucene Infostream
265 To aid in advanced debugging, Lucene provides an "InfoStream"
266 of detailed information when indexing.
268 Setting The value to true will instruct the underlying Lucene
269 IndexWriter to write its debugging info the specified file

429 <!-- Solr Internal Query Caches
431 There are two implementations of cache available for Solr,
432 LRUCache, based on a synchronized LinkedHashMap, and
433 FastLRUCache, based on a ConcurrentHashMap.
435 FastLRUCache has faster gets and slower puts in single
436 threaded operation and thus is generally faster than LRUCache
437 when the hit ratio of the cache is high (> 75%), and may be
438 faster under other scenarios on multi-cpu systems.
443 Cache used by SolrIndexSearcher for filters (DocSets),
444 unordered sets of *all* documents that match a query. When a
445 new searcher is opened, its caches may be prepopulated or
446 "autowarmed" using data from caches in the old searcher.
447 autowarmCount is the number of items to prepopulate. For
448 LRUCache, the autowarmed items will be the most recently
452 class - the SolrCache implementation LRUCache or
453 (LRUCache or FastLRUCache)
454 size - the maximum number of entries in the cache
455 initialSize - the initial capacity (number of entries) of
456 the cache. (see java.util.HashMap)
457 autowarmCount - the number of entries to prepopulate from
460 <filterCache class="solr.FastLRUCache"
465 <!-- Query Result Cache
467 Caches results of searches - ordered lists of document ids
468 (DocList) based on a query, a sort, and the range of documents requested.
470 <queryResultCache class="solr.LRUCache"
477 Caches Lucene Document objects (the stored fields for each
478 document). Since Lucene internal document ids are transient,
479 this cache will not be autowarmed.
481 <documentCache class="solr.LRUCache"
486 <!-- Field Value Cache
488 Cache used to hold field values that are quickly accessible
489 by document id. The fieldValueCache is created by default
490 even if not configured here.
493 <fieldValueCache class="solr.FastLRUCache"
501 Example of a generic cache. These caches may be accessed by
502 name through SolrIndexSearcher.getCache(),cacheLookup(), and
503 cacheInsert(). The purpose is to enable easy caching of
504 user/application level data. The regenerator argument should
505 be specified as an implementation of solr.CacheRegenerator
506 if autowarming is desired.
509 <cache name="myUserCache"
510 class="solr.LRUCache"
514 regenerator="com.mycompany.MyRegenerator"
519 <!-- Lazy Field Loading
521 If true, stored fields that are not requested will be loaded
522 lazily. This can result in a significant speed improvement
523 if the usual case is to not load all stored fields,
524 especially if the skipped fields are large compressed text
527 <enableLazyFieldLoading>true</enableLazyFieldLoading>
529 <!-- Use Filter For Sorted Query
531 A possible optimization that attempts to use a filter to
532 satisfy a search. If the requested sort does not include
533 score, then the filterCache will be checked for a filter
534 matching the query. If found, the filter will be used as the
535 source of document ids, and then the sort will be applied to
538 For most situations, this will not be useful unless you
539 frequently get the same search repeatedly with different sort
540 options, and none of them ever use "score"
543 <useFilterForSortedQuery>true</useFilterForSortedQuery>
546 <!-- Result Window Size
548 An optimization for use with the queryResultCache. When a search
549 is requested, a superset of the requested number of document ids
550 are collected. For example, if a search for a particular query
551 requests matching documents 10 through 19, and queryWindowSize is 50,
552 then documents 0 through 49 will be collected and cached. Any further
553 requests in that range can be satisfied via the cache.

564 Various IndexSearcher related events can trigger Listeners to
567 newSearcher - fired whenever a new searcher is being prepared
568 and there is a current searcher handling requests (aka

570 prevent long request times for certain requests.

622 This section contains instructions for how the SolrDispatchFilter
623 should behave when processing requests for this SolrCore.
625 handleSelect is a legacy option that affects the behavior of requests
626 such as /select?qt=XXX
628 handleSelect="true" will cause the SolrDispatchFilter to process
629 the request and dispatch the query to a handler specified by the
630 "qt" param, assuming "/select" isn't already registered.
632 handleSelect="false" will cause the SolrDispatchFilter to
633 ignore "/select" requests, resulting in a 404 unless a handler
634 is explicitly registered with the name "/select"
636 handleSelect="true" is not recommended for new users, but is the default
637 for backwards compatibility
639 <requestDispatcher handleSelect="false" >
642 These settings indicate how Solr Requests may be parsed, and
643 what restrictions may be placed on the ContentStreams from
646 enableRemoteStreaming - enables use of the stream.file
647 and stream.url parameters for specifying remote streams.
649 multipartUploadLimitInKB - specifies the max size of
650 Multipart File Uploads that Solr will allow in a Request.
653 The settings below authorize Solr to fetch remote files, You
654 should make sure your system has some authentication before
655 using enableRemoteStreaming="true"
658 <requestParsers enableRemoteStreaming="true"
659 multipartUploadLimitInKB="2048000" />
663 Set HTTP caching related parameters (for proxy caches and clients).
665 The options below instruct Solr not to output any HTTP Caching
668 <httpCaching never304="true" />
669 <!-- If you include a <cacheControl> directive, it will be used to
670 generate a Cache-Control header (as well as an Expires header
671 if the value contains "max-age=")
673 By default, no Cache-Control header is generated.
675 You can use the <cacheControl> option even if you have set
679 <httpCaching never304="true" >
680 <cacheControl>max-age=30, public</cacheControl>
683 <!-- To enable Solr to respond with automatically generated HTTP
684 Caching headers, and to response to Cache Validation requests
685 correctly, set the value of never304="false"
687 This will cause Solr to generate Last-Modified and ETag
688 headers based on the properties of the Index.
690 The following options can also be specified to affect the
691 values of these headers...
693 lastModFrom - the default value is "openTime" which means the
694 Last-Modified value (and validation against If-Modified-Since
695 requests) will all be relative to when the current Searcher
696 was opened. You can change it to lastModFrom="dirLastMod" if
697 you want the value to exactly correspond to when the physical
698 index was last modified.
700 etagSeed="..." is an option you can change to force the ETag
701 header (and validation against If-None-Match requests) to be
702 different even if the index has not changed (ie: when making
703 significant changes to your config file)
705 (lastModifiedFrom and etagSeed are both ignored if you use
706 the never304="true" option)

716 <!-- Request Handlers
718 http://wiki.apache.org/solr/SolrRequestHandler
720 Incoming queries will be dispatched to a specific handler by name
721 based on the path specified in the request.
723 Legacy behavior: If the request path uses "/select" but no Request
724 Handler has that name, and if handleSelect="true" has been specified in
725 the requestDispatcher, then the Request Handler is dispatched based on
726 the qt parameter. Handlers without a leading '/' are accessed this way
727 like so: http://host/app/[core/]select?qt=name If no qt is
728 given, then the requestHandler that declares default="true" will be
729 used or the one named "standard".
731 If a Request Handler is declared with startup="lazy", then it will
732 not be initialized until the first request that uses it.
737 http://wiki.apache.org/solr/SearchHandler
739 For processing Search Queries, the primary Request Handler
740 provided with Solr is "SearchHandler" It delegates to a sequent
741 of SearchComponents (see below) and supports distributed
742 queries across multiple shards

949 To override the request content type and force a specific

989 <!-- Field Analysis Request Handler
991 RequestHandler that provides much the same functionality as
992 analysis.jsp. Provides the ability to specify multiple field
993 types and field names in the same request and outputs
994 index-time and query-time analysis for each of them.
996 Request parameters are:
997 analysis.fieldname - field name whose analyzers are to be used
999 analysis.fieldtype - field type whose analyzers are to be used
1000 analysis.fieldvalue - text for index-time analysis
1001 q (or analysis.q) - text for query time analysis
1002 analysis.showmatch (true|false) - When set to true and when
1003 query analysis is performed, the produced tokens of the
1004 field value analysis will be marked as "matched" for every
1005 token that is produces by the query analysis

1012 <!-- Document Analysis Handler
1014 http://wiki.apache.org/solr/AnalysisRequestHandler
1016 An analysis handler that provides a breakdown of the analysis
1017 process of provided documents. This handler expects a (single)
1018 content stream with the following format:
1022 <field name="id">1</field>
1023 <field name="name">The Name</field>
1024 <field name="text">The Text Value</field>
1031 Note: Each document must contain a field which serves as the
1032 unique key. This key is used in the returned response to associate
1033 an analysis breakdown to the analyzed document.
1035 Like the FieldAnalysisRequestHandler, this handler also supports
1036 query analysis by sending either an "analysis.query" or "q"
1037 request parameter that holds the query text to be analyzed. It
1038 also supports the "analysis.showmatch" parameter which when set to
1039 true, all field tokens that match the query tokens will be marked

1142 <searchComponent name="stats" class="solr.StatsComponent" />

1145 Default configuration in a requestHandler would look like:
1147 <arr name="components">
1151 <str>highlight</str>
1156 If you register a searchComponent to one of the standard names,
1157 that will be used instead of the default.

1592 An example dedup update processor that creates the "id" field
1593 on the fly based on the hash code of some other fields. This
1594 example has overwriteDupes set to false since we are using the
1595 id field as the signatureField and Solr will maintain
1596 uniqueness based on that anyway.

1617 written to field language_s. No field name mapping is done.

1619 making this example suitable for detecting languages form full-text
1620 rich documents injected via ExtractingRequestHandler.

1737 To add a constant value to all docs, use:
1738 <transformer name="mytrans2" class="org.apache.solr.response.transform.ValueAugmenterFactory" >
1739 <int name="value">5</int>
