Jim Ferenczi commented on LUCENE-8448:
--------------------------------------
Here is a new patch that restores the unit tests. The previous patch also hits
some random failures in {{CheckHits#doCheckMaxScores}} because we skip
documents with a score equals to the minimum score. To protect against this
issue I changed the propagation to use the first float before minScore instead
of minScore directly. The new patch passes all random tests and showed similar
performances.
