>
> CustomScoreQuery wrongly applies boost^2 instead of boost.
> It wrongly incorporates its boost into the normalization factor passed down
> to subquery (like booleanquery does) and *also* multiplies it directly in its
> scorer.
> The only reason the test passes today is because it compares raw score
> magnitudes when querynorm is on, which normalizes this away.
> Changing the test to use newSearcher() demonstrates the brokenness.
