Assuming the service solr service restart does its job, I think the only thing I would do is to completely remove the data directory content, instead of just running the delete query.
Bare in mind that when you delete a document in Solr, this is marked as deleted, but it takes potentially a while until it really leaves the index ( after a successful segment merge). This could bring to potential conflict in the data structures when documents of different schemas are in the index. I don't know if it is your case, but I would double check. ----- --------------- Alessandro Benedetti Search Consultant, R&D Software Engineer, Director Sease Ltd. - www.sease.io -- View this message in context: http://lucene.472066.n3.nabble.com/multiValued-false-is-not-working-in-Solr-6-4-in-RHEL-CentOS-tp4346939p4346945.html Sent from the Solr - User mailing list archive at Nabble.com.
