ASF subversion and git services commented on LUCENE-10418: ---------------------------------------------------------- Commit 1dcb64b492b33f2adc3735458eefbc80e8feb1ef in lucene's branch refs/heads/main from Adrien Grand [ https://gitbox.apache.org/repos/asf?p=lucene.git;h=1dcb64b ] LUCENE-10418: Move CHANGES to the correct section. > Improve Query rewriting for non-scoring clauses > ----------------------------------------------- > > Key: LUCENE-10418 > URL: https://issues.apache.org/jira/browse/LUCENE-10418 > Project: Lucene - Core > Issue Type: Task > Reporter: Adrien Grand > Priority: Minor > Time Spent: 1.5h > Remaining Estimate: 0h > > Query rewriting is occasionally important for performance, e.g. it may allow > using an optimized bulk scorer instead of the default bulk scorer like in the > example from LUCENE-10412. > One case when we could simplify queries is in the non-scoring case. All > layers of query wrappers that only affect scoring like BoostQuery and > ConstantScore query can be removed, which might help identify new > opportunities for rewriting. For instance, we have several rewrite rules that > optimize for MatchAllDocsQuery and would fail to recognize it if it is behind > a ConstantScoreQuery or a BoostQuery. Boolean queries can also simplify > themselves in the non-scoring case, by changing MUST clauses to FILTER > clauses, or removing fully optional SHOULD clauses. -- This message was sent by Atlassian Jira (v8.20.1#820001) --------------------------------------------------------------------- To unsubscribe, e-mail: issues-unsubscr...@lucene.apache.org For additional commands, e-mail: issues-h...@lucene.apache.org
