Zach Chen commented on LUCENE-10480: ------------------------------------ Hi [~jpountz] , this issue reminded me of our experiments last year implementing BMM scorer for pure disjunction, which [showed about 20% ~ 40% improvement for OrHighHigh and OrHighMed queries|[https://github.com/apache/lucene/pull/101#issuecomment-840255508].] Do you think we should continue to explore in that direction, or there might be better / simpler algorithms we could look into? > Specialize 2-clauses disjunctions > --------------------------------- > > Key: LUCENE-10480 > URL: https://issues.apache.org/jira/browse/LUCENE-10480 > Project: Lucene - Core > Issue Type: Task > Reporter: Adrien Grand > Priority: Minor > > WANDScorer is nice, but it also has lots of overhead to maintain its > invariants: one linked list for the current candidates, one priority queue of > scorers that are behind, another one for scorers that are ahead. All this > could be simplified in the 2-clauses case, which feels worth specializing for > as it's very common that end users enter queries that only have two terms? -- This message was sent by Atlassian Jira (v8.20.7#820007) --------------------------------------------------------------------- To unsubscribe, e-mail: issues-unsubscr...@lucene.apache.org For additional commands, e-mail: issues-h...@lucene.apache.org
