the postings lists and per-document values in the fieldType element

|

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

http://wiki.apache.org/solr/UpdateXmlMessages

|
triggering a new commit.
|
|
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.
|
|
|
|
If the updateLog is enabled, then it's highly recommended to

have some sort of hard autoCommit to limit the log size.

<!-- IndexReaderFactory
|
|
|
|
Use the following format to specify a custom IndexReaderFactory,

|
which allows for alternate IndexReader implementations.
|
|
|
|
** Experimental Feature **
|
|
|
|
Please note - Using a custom IndexReaderFactory may prevent

certain other features from working. The API to

|
IndexReaderFactory may change without warning or may even be
|
|
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
|
|
correctly. See SOLR-1366 for details.

|
|
|

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

POST. You can use POST to pass request parameters not
|

fitting into the URL.

addHttpRequestToContext - if set to true, it will instruct

|

|
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)
|

the never304="true" option)

For processing Search Queries, the primary Request Handler

queries across multiple shards
|

that may also be desired (perhaps as a result of faceted searching).
|
|

NOTE: there is *absolutely* nothing a client can do to prevent these

<!-- 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>

|

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

<int name="value">5</int>

<transformer name="mytrans3" class="org.apache.solr.response.transform.ValueAugmenterFactory" >

<double name="defaultValue">5</double>
