       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 example has overwriteDupes
       set to false since we are using the id field as the signatureField and Solr
       will maintain uniqueness based on that anyway.

       You have to link the chain to an update handler above to use it ie:
