I'm upgrading a plugin from Solr 4.3.1 to Solr 5.2.1 that uses the Lucene API "ConstantScoreQuery class". The code calls, "getFilter()" on a ConstantScoreQuery object which was available from 4.3.1 to Solr 5.0.0 as shown in the API documentation, but has been removed in 5.1.0. I tried to look at both JIRA and CHANGES.TXT files and couldn't find any information it's removal.
Why was it removed? What should I use instead to get the "Filter" that was associated with ConstantScoreQuery so that I can get the associated "DocSetID"? Thanks, Bob
