Adrien Grand commented on LUCENE-7996: -------------------------------------- This might be a better option indeed. > Should we require positive scores? > ---------------------------------- > > Key: LUCENE-7996 > URL: https://issues.apache.org/jira/browse/LUCENE-7996 > Project: Lucene - Core > Issue Type: Wish > Reporter: Adrien Grand > Priority: Minor > Attachments: LUCENE-7996.patch > > > Having worked on MAXSCORE recently, things would be simpler if we required > that scores are positive. Practically, this would mean > - forbidding/fixing similarities that may produce negative scores (we have > some of them) > - forbidding things like negative boosts > - fixing the scoring formula of some queries like {{BoostingQuery}} (which > subtracts a score to another score) so that the end result may never be > negative > So I'd be curious to have opinions whether this would be a sane requirement > or whether we need to be able to cope with negative scores eg. because some > similarities that we want to support produce negative scores by design. -- This message was sent by Atlassian JIRA (v6.4.14#64029) --------------------------------------------------------------------- To unsubscribe, e-mail: dev-unsubscr...@lucene.apache.org For additional commands, e-mail: dev-h...@lucene.apache.org
