Robert Muir resolved LUCENE-8031. --------------------------------- Resolution: Fixed Fix Version/s: master (8.0) > DOCS_ONLY fields set incorrect length norms > ------------------------------------------- > > Key: LUCENE-8031 > URL: https://issues.apache.org/jira/browse/LUCENE-8031 > Project: Lucene - Core > Issue Type: Bug > Reporter: Robert Muir > Priority: Major > Fix For: master (8.0) > > Attachments: LUCENE-8031.patch > > > Term frequencies are discarded in the DOCS_ONLY case from the postings list > but they still count against the length normalization, which looks like it > may screw stuff up. > I ran some quick experiments on LUCENE-8025, by encoding > fieldInvertState.getUniqueTermCount() and it seemed worth fixing (e.g. 20% or > 30% improvement potentially). Happy to do testing for real, if we want to fix. > But this seems tricky, today you can downgrade to DOCS_ONLY on the fly, and > its hard for me to think about that case (i think its generally screwed up > besides this, but still). -- This message was sent by Atlassian JIRA (v7.6.3#76005) --------------------------------------------------------------------- To unsubscribe, e-mail: dev-unsubscr...@lucene.apache.org For additional commands, e-mail: dev-h...@lucene.apache.org
