  <!-- To enable dynamic schema REST APIs, use the following for <schemaFactory>: -->
  
       <schemaFactory class="ManagedIndexSchemaFactory">
         <bool name="mutable">true</bool>
         <str name="managedSchemaResourceName">managed-schema</str>
       </schemaFactory>
       
 <!--  When ManagedIndexSchemaFactory is specified, Solr will load the schema from
       the resource named in 'managedSchemaResourceName', rather than from schema.xml.
       Note that the managed schema resource CANNOT be named schema.xml.  If the managed
       schema does not exist, Solr will create it after reading schema.xml, then rename
       'schema.xml' to 'schema.xml.bak'. 
       
       Do NOT hand edit the managed schema - external modifications will be ignored and
       overwritten as a result of schema modification REST API calls.
       When ManagedIndexSchemaFactory is specified with mutable = true, schema
       modification REST API calls will be allowed; otherwise, error responses will be
       sent back for these requests. 
  -->
  <!-- <schemaFactory class="ClassicIndexSchemaFactory"/> -->

The fcrepo-message-consumer SolrIndexer implementation does not commit upon updates.  In order to see the changes, you must configure Solr to have a commit strategy that is appropriate for your use.  Resource removal events do trigger a commit.

    <!-- AutoCommit

         Perform a hard commit automatically under certain conditions.
         Instead of enabling autoCommit, consider using "commitWithin"
         when adding documents. 

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

         maxDocs - Maximum number of documents to add since the last
                   commit before automatically triggering a new commit.

         maxTime - Maximum amount of time in ms that is allowed to pass
                   since a document was added before automatically
                   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.
      -->
     <autoCommit> 
       <maxTime>${solr.autoCommit.maxTime:15000}</maxTime> 
       <openSearcher>false</openSearcher>
