> 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.
