Hoss Man created LUCENE-6887: -------------------------------- Summary: 5x: backport ClassicSimilarity, mark DefaultSimilarity deprecated & update javadocs to mention ClassicSim vs. BM25Sim Key: LUCENE-6887 URL: https://issues.apache.org/jira/browse/LUCENE-6887 Project: Lucene - Core Issue Type: Task Reporter: Hoss Man Assignee: Hoss Man Fix For: 5.4
LUCENE-6789 changed the default Similarity on trunk to BM25, and renamed DefaultSimiliarity to ClassicSimilarity for backcompat w/o confusion about the "default" name. But nothing related to this change was committed to the 5x branch. On the 5x branch we should: * mark DefaultSimiliarity deprecated * provide a ClassicSimilarity for 5.x users to switch to to resolve deprecations w/o changing behavior (and allow smooth upgrade to 6.x later) * note in the DefaultSimiliarity javadocs that starting with 6.0 BM25 will be the recommended default and users should investigate it -- This message was sent by Atlassian JIRA (v6.3.4#6332) --------------------------------------------------------------------- To unsubscribe, e-mail: dev-unsubscr...@lucene.apache.org For additional commands, e-mail: dev-h...@lucene.apache.org
