> 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.
