------------------------------------
Summary: Implement Block-Max WAND
Key: LUCENE-8135
URL: https://issues.apache.org/jira/browse/LUCENE-8135
Project: Lucene - Core
Issue Type: Improvement
Reporter: Adrien Grand
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)|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).
