Adrien Grand updated LUCENE-8060: --------------------------------- Summary: Enable top-docs collection optimizations by default (was: Require users to tell us whether they need total hit counts) > Enable top-docs collection optimizations by default > --------------------------------------------------- > > Key: LUCENE-8060 > URL: https://issues.apache.org/jira/browse/LUCENE-8060 > Project: Lucene - Core > Issue Type: Improvement > Reporter: Adrien Grand > Priority: Minor > Fix For: master (8.0) > > > We are getting optimizations when hit counts are not required (sorted > indexes, MAXSCORE, short-circuiting of phrase queries) but our users won't > benefit from them unless we disable exact hit counts by default or we require > them to tell us whether hit counts are required. > I think making hit counts approximate by default is going to be a bit trappy, > so I'm rather leaning towards requiring users to tell us explicitly whether > they need total hit counts. I can think of two ways to do that: either by > passing a boolean to the IndexSearcher constructor or by adding a boolean to > all methods that produce TopDocs instances. I like the latter better but I'm > open to discussion or other ideas? -- 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
