  <!-- IndexReaderFactory

       Use the following format to specify a custom IndexReaderFactory,

       ** 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.

         FastLRUCache has faster gets and slower puts in single
         threaded operation and thus is generally faster than LRUCache

         "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.

         enableRemoteStreaming - enables use of the stream.file
         and stream.url parameters for specifying remote streams.

         multipartUploadLimitInKB - specifies the max size of
         Multipart File Uploads that Solr will allow in a Request.

         *** WARNING ***
         The settings below authorize Solr to fetch remote files, You

         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)

         the never304="true" option)

  <!-- Request Handlers

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

       incoming queries will be dispatched to the correct handler
       based on the path or the qt (query type) param.

       Names starting with a '/' are accessed with the a path equal to
       the registered name.  Names without a leading '/' are accessed
       with: http://host/app/[core/]select?qt=name

       If a /select request is processed with out a qt param
       specified, the requestHandler that declares default="true" will
       be used.

       If a Request Handler is declared with startup="lazy", then it will
       not be initialized until the first request that uses it.

  <!-- SearchHandler

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

       For processing Search Queries, the primary Request Handler
       provided with Solr is "SearchHandler" It delegates to a sequent
       of SearchComponents (see below) and supports distributed
       queries across multiple shards
    -->

         to identify values which should be appended to the list of
         multi-val params from the query (or the existing "defaults").
      -->
    <!-- In this example, the param "fq=instock:true" would be appended to
         any query time fq params the user may specify, as a mechanism for
         partitioning the index, independent of any user selected filtering
         that may also be desired (perhaps as a result of faceted searching).

         NOTE: there is *absolutely* nothing a client can do to prevent these
         "appends" values from being used, so don't use this mechanism
         unless you are sure you always want it.

         specified here are used regardless of what values may be specified
         in either the query, the "defaults", or the "appends" params.

         In this example, the facet.field and facet.query params would
         be fixed, limiting the facets clients can use.  Faceting is
         not turned on by default - but if the client does specify
         facet=true in the request, these are the only facets they
         will be able to see counts for; regardless of what other
         facet.field or facet.query params they may specify.

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

  <!-- Document Analysis Handler

       http://wiki.apache.org/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>
         ...
       </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".

       <searchComponent name="mlt"       class="solr.MoreLikeThisComponent" />

       <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"
