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 ---- http://www.solr-start.com/ - Resources for Solr users, new and experienced On 7 March 2017 at 07:30, ~$alpha` <lavesh.ra...@gmail.com> wrote: > *SOLR_URL/update -d \' > [ > {"id" : "1", > "ONLINE" : {"set":"1"} > } > ]'* > > I am using solr6.3.
