    Description

      This is a follow-up issue from discussion https://github.com/apache/lucene/pull/972#discussion_r909300200 . Currently in the implementation of BlockMaxMaxscoreScorer, there's duplicated computation of summing up scores from essential list scorers. We would like to see if this duplicated computation can be cached without introducing much overhead or data structure that might out-weight the benefit of caching.
