Use the following format to specify a custom IndexReaderFactory,

** Features that may not work with custom IndexReaderFactory **

The ReplicationHandler assumes a disk-resident index. Using a

|
|
|
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.

<!-- Use Filter For Sorted Query
|
|
|
|
A possible optimization that attempts to use a filter to

|
|
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"

An optimization for use with the queryResultCache. When a search

|
|
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

the request and dispatch the query to a handler specified by the

|
|
|
handleSelect="false" will cause the SolrDispatchFilter to

is explicitly registered with the name "/select"

for backwards compatibility

These settings indicate how Solr Requests may be parsed, and

enableRemoteStreaming - enables use of the stream.file
|

|
|
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

|
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

|
|
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)

<!-- 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
|
|
not be initialized until the first request that uses it.

|

In this example, the facet.field and facet.query params would

analysis.fieldvalue - text for index-time analysis

<!-- Document Analysis Handler
|
|
|
|
http://wiki.apache.org/solr/AnalysisRequestHandler
|
|
|
|
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>
|
|
<field name="name">The Name</field>
|
|
<field name="text">The Text Value</field>
|
|
</doc>
|
|
<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".

|
|

http://wiki.apache.org/solr/SolrReplication
|
|
|

It is also necessary for SolrCloud to function (in Cloud mode, the

|
replication handler is used to bulk transfer segments when nodes

<!-- Search Components
|
|
|
|
Search components are registered to SolrCore and used by
|
|
instances of SearchHandler (which can access them by name)
|
|
|
|
By default, the following components are available:
|
|
|
|
<searchComponent name="query" class="solr.QueryComponent" />
|
|
<searchComponent name="facet" class="solr.FacetComponent" />
|
|
<searchComponent name="mlt" class="solr.MoreLikeThisComponent" />
|
|
<searchComponent name="highlight" class="solr.HighlightComponent" />
|
|
<searchComponent name="stats" class="solr.StatsComponent" />
|
|
<searchComponent name="debug" class="solr.DebugComponent" />
|
|
|
|
Default configuration in a requestHandler would look like:
|
|
|
|
<arr name="components">
|
|
<str>query</str>
|
|
<str>facet</str>
|
|
<str>mlt</str>
|
|
<str>highlight</str>
|
|
<str>stats</str>
|
|
<str>debug</str>
|
|
</arr>
|
|
|
|
If you register a searchComponent to one of the standard names,
|
|
that will be used instead of the default.
|
|
|
|
To insert components before or after the 'standard' components, use:
|
|
|
|
<arr name="first-components">
|
|
<str>myFirstComponentName</str>
|
|
</arr>
|
|
|
|
<arr name="last-components">
|
|
<str>myLastComponentName</str>
|
|
</arr>
|
|
|

NOTE: The component registered with the name "debug" will
|
|
always be executed after the "last-components"

<!-- Query Parsers
|
|
|
|
http://wiki.apache.org/solr/SolrQuerySyntax
|
|
|
|
Multiple QParserPlugins can be registered by name, and then
|
|
used in either the "defType" param for the QueryComponent (used
|
|
by SearchHandler) or in LocalParams
|
|

|
|
<!-- example of registering a query parser -->
|
|
<!--
|
|
<queryParser name="myparser" class="com.mycompany.MyQParserPlugin"/>

|
<!-- Function Parsers
|
|
|
|
http://wiki.apache.org/solr/FunctionQuery
|
|
|
|
Multiple ValueSourceParsers can be registered by name, and then
|
|
used as function names when using the "func" QParser.
|
|
-->
|
|
<!-- example of registering a custom function parser -->
|
|
<!--
|
|
<valueSourceParser name="myfunc"
|
|
class="com.mycompany.MyValueSourceParser" />
|

<!-- Document Transformers
|
|
http://wiki.apache.org/solr/DocTransformers
|
|
-->
|
|
<!--
|
|
Could be something like:
|
|
<transformer name="db" class="com.mycompany.LoadFromDatabaseTransformer" >
|
|
<int name="connection">jdbc://....</int>
|
|
</transformer>
|
|
|
|
To add a constant value to all docs, use:
|
|
<transformer name="mytrans2" class="org.apache.solr.response.transform.ValueAugmenterFactory" >
|
|
<int name="value">5</int>
|
|
</transformer>
|
|
|
|
If you want the user to still be able to change it with _value:something_ use this:
|
|
<transformer name="mytrans3" class="org.apache.solr.response.transform.ValueAugmenterFactory" >
|
|
<double name="defaultValue">5</double>
|
|
</transformer>
|
|
If you are using the QueryElevationComponent, you may wish to mark documents that get boosted. The
|
|
EditorialMarkerFactory will do exactly that:
|
|
<transformer name="qecBooster" class="org.apache.solr.response.transform.EditorialMarkerFactory" />
