this file, see http://wiki.apache.org/solr/SolrConfigXml.
-->
<config>
<!-- In all configuration below, a prefix of "solr." for class names
is an alias that causes solr to search appropriate packages,
including org.apache.solr.(search|update|request|core|analysis)
You may also specify a fully qualified Java classname if you
have your own custom plugins.
-->
<!-- Controls what version of Lucene various components of Solr
adhere to. Generally, you want to use the latest version to
get all bug fixes and improvements. It is highly recommended
that you fully re-index after changing this setting as it can
affect both how text is indexed and queried.
-->
<luceneMatchVersion>8.11.1</luceneMatchVersion>
<!-- <lib/> directives can be used to instruct Solr to load any Jars
identified and use them to resolve any "plugins" specified in
your solrconfig.xml or schema.xml (ie: Analyzers, Request
Handlers, etc...).
All directories and paths are resolved relative to the
instanceDir.
Please note that <lib/> directives are processed in the order
that they appear in your solrconfig.xml file, and are "stacked"
on top of each other when building a ClassLoader - so if you have
plugin jars with dependencies on other jars, the "lower level"
dependency jars should be loaded first.
If a "./lib" directory exists in your instanceDir, all files
found in it are included as if you had used the following
syntax...
<lib dir="./lib" />
-->
<!-- A 'dir' option by itself adds any files found in the directory
to the classpath, this is useful for including all jars in a
directory.
When a 'regex' is specified in addition to a 'dir', only the
files in that directory which completely match the regex
(anchored on both ends) will be included.
If a 'dir' option (with or without a regex) is used and nothing
is found that matches, a warning will be logged.
The examples below can be used to load some solr-contribs along
with their external dependencies.
-->
<lib dir="${solr.install.dir:../../../..}/contrib/extraction/lib" regex=".*\.jar" />
<lib dir="${solr.install.dir:../../../..}/dist/" regex="solr-cell-\d.*\.jar" />
<lib dir="${solr.install.dir:../../../..}/contrib/clustering/lib/" regex=".*\.jar" />

<lib dir="${solr.install.dir:../../../..}/dist/" regex="solr-dataimporthandler-.*\.jar" />
<lib dir="${solr.install.dir:../../../..}/dist/" regex="postgresql-.*\.jar" />
<!-- an exact 'path' can be used instead of a 'dir' to specify a
specific jar file. This will cause a serious error to be logged
if it can't be loaded.
-->
<!--
<lib path="../a-jar-that-does-not-exist.jar" />
-->
<!-- Data Directory
Used to specify an alternate directory to hold all index data
other than the default ./data under the Solr home. If
replication is in use, this should match the replication
configuration.
-->
<dataDir>${solr.data.dir:}</dataDir>
<!-- The DirectoryFactory to use for indexes.
solr.StandardDirectoryFactory is filesystem
based and tries to pick the best implementation for the current
JVM and platform. solr.NRTCachingDirectoryFactory, the default,
wraps solr.StandardDirectoryFactory and caches small files in memory
for better NRT performance.
One can force a particular implementation via solr.MMapDirectoryFactory,
solr.NIOFSDirectoryFactory, or solr.SimpleFSDirectoryFactory.
solr.RAMDirectoryFactory is memory based and not persistent.
-->
<directoryFactory name="DirectoryFactory"
class="${solr.directoryFactory:solr.NRTCachingDirectoryFactory}"/>
<!-- The CodecFactory for defining the format of the inverted index.
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)
or "BEST_COMPRESSION".
-->
<codecFactory class="solr.SchemaCodecFactory"/>
<!-- ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
Index Config - These settings control low-level behavior of indexing
Most example settings here show the default value, but are commented
out, to more easily see where customizations have been made.
Note: This replaces <indexDefaults> and <mainIndex> from older versions
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ -->
<indexConfig>
<!-- maxFieldLength was removed in 4.0. To get similar behavior, include a
LimitTokenCountFilterFactory in your fieldType definition. E.g.
<filter class="solr.LimitTokenCountFilterFactory" maxTokenCount="10000"/>
-->
<!-- Maximum time to wait for a write lock (ms) for an IndexWriter. Default: 1000 -->
<!-- <writeLockTimeout>1000</writeLockTimeout> -->
<!-- Expert: Enabling compound file will use less files for the index,
using fewer file descriptors on the expense of performance decrease.
Default in Lucene is "true". Default in Solr is "false" (since 3.6) -->
<!-- <useCompoundFile>false</useCompoundFile> -->
<!-- ramBufferSizeMB sets the amount of RAM that may be used by Lucene
indexing for buffering added documents and deletions before they are
flushed to the Directory.
maxBufferedDocs sets a limit on the number of documents buffered
before flushing.
If both ramBufferSizeMB and maxBufferedDocs is set, then
Lucene will flush based on whichever limit is hit first. -->
<!-- <ramBufferSizeMB>100</ramBufferSizeMB> -->
<!-- <maxBufferedDocs>1000</maxBufferedDocs> -->
<!-- Expert: Merge Policy
The Merge Policy in Lucene controls how merging of segments is done.
The default since Solr/Lucene 3.3 is TieredMergePolicy.
The default since Lucene 2.3 was the LogByteSizeMergePolicy,
Even older versions of Lucene used LogDocMergePolicy.
-->
<!--
<mergePolicyFactory class="org.apache.solr.index.TieredMergePolicyFactory">
<int name="maxMergeAtOnce">10</int>
<int name="segmentsPerTier">10</int>
<double name="noCFSRatio">0.1</double>
</mergePolicyFactory>
-->
<!-- Expert: Merge Scheduler
The Merge Scheduler in Lucene controls how merges are
performed. The ConcurrentMergeScheduler (Lucene 2.3 default)
can perform merges in the background using separate threads.
The SerialMergeScheduler (Lucene 2.2 default) does not.
-->
<!--
<mergeScheduler class="org.apache.lucene.index.ConcurrentMergeScheduler"/>
-->
<!-- LockFactory
This option specifies which Lucene LockFactory implementation
to use.
single = SingleInstanceLockFactory - suggested for a
read-only index or when there is no possibility of

is recommended (see below).
"dir" - the target directory for transaction logs, defaults to the
solr data directory.
"numVersionBuckets" - sets the number of buckets used to keep
track of max version values when checking for re-ordered
updates; increase this value to reduce the cost of
synchronizing access to version buckets during high-volume

openSearcher - if false, the commit causes recent index changes
to be flushed to stable storage, but does not cause a new
searcher to be opened to make those changes visible.

removed from future releases if the problems cannot be
resolved.
** Features that may not work with custom IndexReaderFactory **
The ReplicationHandler assumes a disk-resident index. Using a
custom IndexReader implementation may cause incompatibility
with ReplicationHandler and may cause replication to not work

<!-- Solr Internal Query Caches
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.
-->
<!-- Filter Cache
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.
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
the cache. (see java.util.HashMap)
autowarmCount - the number of entries to prepopulate from
and old cache.
maxRamMB - the maximum amount of RAM (in MB) that this cache is allowed
to occupy. Note that when this option is specified, the size
and initialSize parameters are ignored.
-->

<!-- Query Result Cache
Caches results of searches - ordered lists of document ids
(DocList) based on a query, a sort, and the range of documents requested.
Additional supported parameter by LRUCache:

<!-- Custom Cache
Example of a generic cache. These caches may be accessed by
name through SolrIndexSearcher.getCache(),cacheLookup(), and
cacheInsert(). The purpose is to enable easy caching of
user/application level data. The regenerator argument should
be specified as an implementation of solr.CacheRegenerator
if autowarming is desired.

especially if the skipped fields are large compressed text
fields.

<!-- Use Filter For Sorted Query
A possible optimization that attempts to use a filter to
satisfy a search. If the requested sort does not include
score, then the filterCache will be checked for a filter
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
options, and none of them ever use "score"
-->
<!--

<!-- Result Window Size
An optimization for use with the queryResultCache. When a search
is requested, a superset of the requested number of document ids
are collected. For example, if a search for a particular query
requests matching documents 10 through 19, and queryWindowSize is 50,
then documents 0 through 49 will be collected and cached. Any further
requests in that range can be satisfied via the cache.

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.

correctly, set the value of never304="false"
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)
(lastModifiedFrom and etagSeed are both ignored if you use
the never304="true" option)
