Description

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.
