[jira] [Created] (SOLR-12337) Remove QueryWrapperFilter

David Smiley created SOLR-12337:
-----------------------------------

             Summary: Remove QueryWrapperFilter
                 Key: SOLR-12337
                 URL: https://issues.apache.org/jira/browse/SOLR-12337
             Project: Solr
          Issue Type: Sub-task
      Security Level: Public (Default Security Level. Issues are Public)
            Reporter: David Smiley
            Assignee: David Smiley


QueryWrapperFilter has not been needed ever since Filter was changed to extend Query -- LUCENE-1518.  It was retained because there was at least one place in Lucene that had a Filter/Query distinction, but it was forgotten when Filter moved to Solr.  It contains some code that creates a temporary IndexSearcher but forgets to null out the cache on it, and so QueryWrapperFilter can add non-trivial overhead.  We should simply remove it altogether.
