Erick, much thanks for detailing these options. I am currently trying the second one as that seems a little easier and quicker to me.
I successfully deleted documents with IDs after the problem time that I do know to an accuracy of a couple hours. Now, the stats are: numDocs : 2132454075 maxDoc : -2130733352 The former is nicely below 2^31. But I can't seem to get the latter to "decrease" and become positive by deleting further. Should I just run an optimize at this point? I have never manually run an optimize and plan to just hit http://<machine_name>/solr/update?optimize=true Can you confirm this? -- View this message in context: http://lucene.472066.n3.nabble.com/solr-java-lang-NullPointerException-on-select-queries-tp3989974p3990798.html Sent from the Solr - User mailing list archive at Nabble.com.
