    Description

      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.
