-----------------------------------
Summary: reduce/remove usages of CheckHits.EXPLAIN_TOLERANCE_*
Key: LUCENE-8008
URL: https://issues.apache.org/jira/browse/LUCENE-8008
Project: Lucene - Core
Issue Type: Improvement
Reporter: Robert Muir
these tolerance deltas are being (ab)used in various ways in tests. I did some
experimentation and they can almost be removed entirely without too much pain.
LUCENE-7997 fixes all similarities such that score() == explain(). It makes its
possible to actually debug numeric errors and we need to do that if we have
optimizations such as maxscore that care about score values. So I think we
should do the same thing elsewhere in scoring (weight/scorer).
We should at the very least fix tests (such as expression tests) that no longer
need these deltas and can now assert exact values.
