Jan Høydahl updated SOLR-13025: ------------------------------- Fix Version/s: master (8.0) > Replace usage of LegacyBM25Similarity with BM25Similarity > --------------------------------------------------------- > > Key: SOLR-13025 > URL: https://issues.apache.org/jira/browse/SOLR-13025 > Project: Solr > Issue Type: Task > Security Level: Public(Default Security Level. Issues are Public) > Affects Versions: master (8.0) > Reporter: Adrien Grand > Assignee: Jan Høydahl > Priority: Blocker > Fix For: master (8.0) > > > This is a follow-up of LUCENE-8563: Lucene changed its BM25Similarity > implementation to no longer multiply all scores by (k1 + 1). Solr was left > unchanged by replacing uses of BM25Similarity with LegacyBM25Similarity which > returns the same scores as in 7.x. However it would be nice to switch back to > BM25Similarity, either all the time with a note in the migration guide, or > based on the luceneMatchVersion of the collection. -- 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
