Subject Re: Solr Update If Record Exists ?
Date Tue, 07 Mar 2017 15:02:24 GMT
Try adding: _version_:1, as per Optimistic Concurrency feature:
https://cwiki.apache.org/confluence/display/solr/Updating+Parts+of+Documents#UpdatingPartsofDocuments-OptimisticConcurrency

This should work for a single document update. If you are trying to
update multiple document, this is slightly more complicated as there
will be rejections/exceptions generated. Perhaps, it can be combined
with TollerantUpdate URP:
http://www.solr-start.com/javadoc/solr-lucene/org/apache/solr/update/processor/TolerantUpdateProcessorFactory.html

Regards,
   Alex.
P.s. SOLR-9530 may also be interesting, though its primary use case is
somewhat different
