I think as long as I can override the combine it's actually helpful. I think for users the static simple method should remain but I don't think the (non-static) rescore method should be polluted with a Query since that is impl. specifc and can be passed via Ctor args or so but still be hidden if the user uses the simple static API. > Add query rescoring API > ----------------------- > > Key: LUCENE-5489 > URL: https://issues.apache.org/jira/browse/LUCENE-5489 > Project: Lucene - Core > Issue Type: Improvement > Reporter: Michael McCandless > Assignee: Michael McCandless > Fix For: 4.8, 5.0 > > Attachments: LUCENE-5489.patch, LUCENE-5489.patch > > > When costly scoring factors are used during searching, a common > approach is to do a cheaper / basic query first, collect the top few > hundred hits, and then rescore those hits using the more costly > query. > It's not clear/simple to do this with Lucene today; I think we should > make it easier. -- This message was sent by Atlassian JIRA (v6.2#6252) --------------------------------------------------------------------- To unsubscribe, e-mail: dev-unsubscribe@lucene.apache.org For additional commands, e-mail: dev-help@lucene.apache.org
