CustomScoreQuery should support arbitrary Queries
-------------------------------------------------
Key: LUCENE-1608
URL: https://issues.apache.org/jira/browse/LUCENE-1608
Project: Lucene - Java
Issue Type: New Feature
Components: Query/Scoring
Reporter: Steven Bethard
Priority: Minor
CustomScoreQuery only allows the secondary queries to be of type
ValueSourceQuery instead of allowing them to be any type of Query. As a result,
what you can do with CustomScoreQuery is pretty limited.
It would be nice to extend CustomScoreQuery to allow arbitrary Query objects.
Most of the code should stay about the same, though a little more care would
need to be taken in CustomScorer.score() to use 0.0 when the sub-scorer does
not produce a score for the current document.
