|

|
|
|
+ All directories and paths are resolved relative to the

|
|

|
|
|

|
|
|
+ When a 'regex' is specified in addition to a 'dir', only the
|
|

|
|
|
+ (anchored on both ends) will be included.
|
|
|
+
|
|

|

|
|
|
+
|
|
|
+ One can force a particular implementation via solr.MMapDirectoryFactory,
|
|

+ solr.NIOFSDirectoryFactory, or solr.SimpleFSDirectoryFactory.
|

|
|
+ The default implementation is SchemaCodecFactory, which is the official Lucene
|

|
+ index format, but hooks into the schema to provide per-field customization of
|
|
|
+ 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
|
|
|
+ idea to convert back to the official format e.g. via IndexWriter.addIndexes(IndexReader)
|
|
|
+ before upgrading to a newer version to avoid unnecessary reindexing.
|
|
|
+ A "compressionMode" string element can be added to <codecFactory> to choose
|
|
|
+ between the existing compression modes in the default codec: "BEST_SPEED" (default)
|

|
|
|
+ Note that the managed schema resource CANNOT be named schema.xml. If the managed

|
|

|
|
+ There are two implementations of cache available for Solr,
|
|
|
+ LRUCache, based on a synchronized LinkedHashMap, and
|
|
|
+ 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.

|
|
+ Cache used by SolrIndexSearcher for filters (DocSets),
|
|
|
+ unordered sets of *all* documents that match a query. When a
|
|
|
+ new searcher is opened, its caches may be prepopulated or
|
|
|
+ "autowarmed" using data from caches in the old searcher.
|
|
|
+ autowarmCount is the number of items to prepopulate. For
|
|
|
+ LRUCache, the autowarmed items will be the most recently
|
|
|
+ accessed items.

|
+ matching the query. If found, the filter will be used as the

|
|
+ source of document ids, and then the sort will be applied to
|
|
|
+ that.
|
|
|
+
|
|
|
+ For most situations, this will not be useful unless you
|
|
|
+ frequently get the same search repeatedly with different sort
|

|

|
|
|
+ requests matching documents 10 through 19, and queryWindowSize is 50,
|
|
|
+ then documents 0 through 49 will be collected and cached. Any further

|
+ This section contains instructions for how the SolrDispatchFilter
|
|
|

|
|
|
+
|
|
|
+ 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
|

|

|
|
|
+ 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

|
|
|
+ This will cause Solr to generate Last-Modified and ETag
|
|
|
+ headers based on the properties of the Index.
|
|
|
+
|
|
|
+ The following options can also be specified to affect the
|
|
|
+ values of these headers...
|
|
|
+
|
|
|
+ lastModFrom - the default value is "openTime" which means the
|
|
|
+ Last-Modified value (and validation against If-Modified-Since
|
|
|
+ requests) will all be relative to when the current Searcher
|
|
|
+ was opened. You can change it to lastModFrom="dirLastMod" if
|
|
|
+ you want the value to exactly correspond to when the physical
|
|
|
+ index was last modified.
|
|
|
+
|
|
|
+ etagSeed="..." is an option you can change to force the ETag
|
|
|
+ header (and validation against If-None-Match requests) to be
|
|
|
+ different even if the index has not changed (ie: when making
|
|
|
+ significant changes to your config file)
|
|

|
|
|
+
|
|
|
+ An analysis handler that provides a breakdown of the analysis
|
|
|
+ process of provided documents. This handler expects a (single)
|
|
|
+ content stream with the following format:
|
|
|
+
|
|
|
+ <docs>
|
|
|
+ <doc>
|
|
|
+ <field name="id">1</field>

|
|

+ <doc>...</doc>
|
|
|
+ <doc>...</doc>
|
|
|
+ ...
|
|
|
+ </docs>
|
|
|
+
|
|
|
+ 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
|
|
|
+ as a "match".
