Kyle Maxwell closed LUCENE-1019.
--------------------------------

       Resolution: Invalid
    Lucene Fields:   (was: [Patch Available, New])

Ok, I'm satisfied with Doron's solution.  It'd be nice to see something like this in some
documentation, somewhere.  The wiki is prolly appropriate.

> CustomScoreQuery's constructor currently accepts a subQuery, and a ValueSourceQuery.
 I would like it to accept multiple ValueSourceQueries.  The workaround of nested CustomScoreQueries
works for simple cases, but it quickly becomes either cumbersome to manage, or impossible
to implement the desired function.
> This patch implements CustomMultiScoreQuery with my desired functionality, and refactors
CustomScoreQuery to implement the special case of a CustomMultiScoreQuery with 0 or 1 ValueSourceQueries.
 This keeps the CustomScoreQuery API intact.
> This patch includes basic tests, more or less taken from the original implementation,
and customized a bit to cover the new cases.
