Thank you for your answer. We've found out that the problem was in our SOLR spec (heliosearch 0.08). There are no crushes, after changing to 4.10.3 (although, there are lot of OOMs while handling query, it's not really strange for 1.1 bil of documents ). Now we are going to try latest Heliosearch.
Is there any way to make 'docValues="true"' without reindexing? -- View this message in context: http://lucene.472066.n3.nabble.com/Field-collapsing-memory-usage-tp4181092p4181108.html Sent from the Solr - User mailing list archive at Nabble.com.
