------------------------------------------
Summary: 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
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.
