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.
