           Summary: Performance improvement in search
           Product: Lucene
           Version: CVS Nightly - Specify date in submission
          Platform: All
        OS/Version: other
            Status: NEW
          Severity: enhancement
          Priority: P2
         Component: Search
        AssignedTo: java-dev@lucene.apache.org
        ReportedBy: john.wang@gmail.com


When search with a Filter!=null, the scorer gathers all the hits and then throws
away the documents not in the filtered set. Seems the work to calculate the
score for the documents thrown away is wasted.

It would be nice to pass the filter into the scorer, and filter out the
documents before scoring is done. 

Thanks
-John
