Adrien Grand created LUCENE-7677: ------------------------------------ Summary: Cache compound filters earlier than regular queries Key: LUCENE-7677 URL: https://issues.apache.org/jira/browse/LUCENE-7677 Project: Lucene - Core Issue Type: Improvement Reporter: Adrien Grand Priority: Minor
Say you keep reusing a boolean filter that looks like "A OR B" and never use the A and B queries out of that boolean query. Currently, after this filter has been used 5 times, we would cache both A, B and "A OR B", which means that cache entries for A and B would only be built for the purpose of building a cache entry for "A OR B", which is wasteful. By caching compound queries a bit earlier, we could make it less likely to happen since: - we only consider queries as consumed if a scorer is pulled - once the boolean query is cached, we stop pulling scorers on the A and B queries -- This message was sent by Atlassian JIRA (v6.3.15#6346) --------------------------------------------------------------------- To unsubscribe, e-mail: dev-unsubscr...@lucene.apache.org For additional commands, e-mail: dev-h...@lucene.apache.org
