However, the range query at some point > gets cached by a querying thread in LRUQueryCache, which negates the > optimization of IndexOrDocValuesQuery for that specific query. > It would be nice to see an asynchronous caching implementation in such cases, > so that queries involving IndexOrDocValuesQuery would have consistent > performance characteristics. -- This message was sent by Atlassian Jira (v8.3.4#803005) --------------------------------------------------------------------- To unsubscribe, e-mail: issues-unsubscr...@lucene.apache.org For additional commands, e-mail: issues-h...@lucene.apache.org
