-----------------------------------
Summary: CustomScoreQuery has broken boosting
Key: LUCENE-4935
URL: https://issues.apache.org/jira/browse/LUCENE-4935
Project: Lucene - Core
Issue Type: Bug
Components: core/query/scoring
Reporter: Robert Muir
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.
