------------------------------------
Summary: ReqOptSumScorer should leverage sub scorers' per-block
max scores
Key: LUCENE-8204
URL: https://issues.apache.org/jira/browse/LUCENE-8204
Project: Lucene - Core
Issue Type: Improvement
Reporter: Adrien Grand
Currently it only looks at max scores on the entire segment. Given that
per-block max scores usually give lower upper bounds of the score, this should
help.
This is especially important for LUCENE-8197 to work well since the main query
would typically be added as a MUST clauses of a boolean query while the query
that scores on features would be a SHOULD clause.
