       All directories and paths are resolved relative to the

       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" />

       If a 'dir' option (with or without a regex) is used and nothing

       Use the following format to specify a custom IndexReaderFactory,

       Please note - Using a custom IndexReaderFactory may prevent

       removed from future releases if the problems cannot be

       The ReplicationHandler assumes a disk-resident index. Using a

       An example dedup update processor that creates the "id" field
       on the fly based on the hash code of some other fields.  This

     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>

      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" />
