      Description

      This issue is about building on top of LUCENE-4198 in order to leverage block maximum scores instead of global maximum scores. This is documented in "Faster Top-k Document Retrieval Using Block-Max Indexes" (http://engineering.nyu.edu/~suel/papers/bmw.pdf) and called BMW (Block-Max WAND).

       

      Using block max scores adds overhead to scorers, but also provides better upper bounds of the scores and is expected to remain efficient in presence of outliers (LUCENE-8087).
