Thanks Shawn. But after making the below changes (making versionable_chain
as default) all my update,inserts & deleteByQuery are failing with the
error "*Error from server at http://localhost:8888/solr/discovery
<http://localhost:8888/solr/discovery>: DistributedUpdateProcessor must
follow DocBasedVersionConstraintsProcessor*"
<updateRequestProcessorChain name="versionable_chain" default="true">
<processor class="solr.DocBasedVersionConstraintsProcessorFactory">
<str name="versionField">doc_version</str>
<bool name="ignoreOldUpdates">false</bool>
</processor>
</updateRequestProcessorChain>
