      Description

      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.
