Overriding values for Carrot2 default algorithm attributes. For a description
of all available attributes, see: http://download.carrot2.org/stable/manual/#chapter.components.
Use attribute key as name attribute of str elements below. These can be further
overridden for individual requests by specifying attribute key as request
parameter name and attribute value as parameter value.

<!-- Update request handler.
Note: Since solr1.1 requestHandlers requires a valid content type header if posted in
the body. For example, curl now requires: -H 'Content-type:text/xml; charset=utf-8'
The response format differs from solr1.1 formatting and returns a standard error code.
To enable solr1.1 behavior, remove the /update handler or change its path

<!--
Analysis request handler. Since Solr 1.3. Use to return how a document is analyzed. Useful
for debugging and as a token server for other types of applications.
This is deprecated in favor of the improved DocumentAnalysisRequestHandler and FieldAnalysisRequestHandler
<requestHandler name="/analysis" class="solr.AnalysisRequestHandler" />
-->
<!--
An analysis handler that provides a breakdown of the analysis process of provided docuemnts. 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 assoicate 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 paraemter that holds the query text to be analyized. 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".
-->
<requestHandler name="/analysis/document" class="solr.DocumentAnalysisRequestHandler"/>
<!--
RequestHandler that provides much the same functionality as analysis.jsp. Provides the ability
to specify multiple field types and field names in the same request and outputs index-time and
query-time analysis for each of them.
Request parameters are:
analysis.fieldname - The field name whose analyzers are to be used
analysis.fieldtype - The field type whose analyzers are to be used
analysis.fieldvalue - The text for index-time analysis
q (or analysis.q) - The text for query time analysis
analysis.showmatch (true|false) - When set to true and when query analysis is performed, the produced
tokens of the field value analysis will be marked as "matched" for every
token that is produces by the query analysis
-->
<requestHandler name="/analysis/field" class="solr.FieldAnalysisRequestHandler"/>
<!-- CSV update handler, loaded on demand -->
<requestHandler name="/update/csv" class="solr.CSVRequestHandler" startup="lazy"/>
<!--
Admin Handlers - This will register all the standard admin RequestHandlers. Adding
this single handler is equivalent to registering:
<requestHandler name="/admin/luke" class="org.apache.solr.handler.admin.LukeRequestHandler" />
<requestHandler name="/admin/system" class="org.apache.solr.handler.admin.SystemInfoHandler" />
<requestHandler name="/admin/plugins" class="org.apache.solr.handler.admin.PluginInfoHandler" />

<requestHandler name="/admin/properties" class="org.apache.solr.handler.admin.PropertiesRequestHandler" />
<requestHandler name="/admin/file" class="org.apache.solr.handler.admin.ShowFileRequestHandler" >
If you wish to hide files under ${solr.home}/conf, explicitly register the ShowFileRequestHandler using:
<requestHandler name="/admin/file" class="org.apache.solr.handler.admin.ShowFileRequestHandler" >
