-------------------------------------
Summary: WANDScorer's handling of 0 and +Infty is backwards
Key: LUCENE-10553
URL: https://issues.apache.org/jira/browse/LUCENE-10553
Project: Lucene - Core
Issue Type: Improvement
Reporter: Adrien Grand
WANDScorer has special logic to deal with corner cases when the sum of the
maximum scores of sub queries is either 0 or +Infty, but both code and tests
have backwards logic regarding this special case, doing +1 instead of -1 and
vice-versa.
This leads to a failed assertion in the case when the sum of the scores of the
sub queries overflows, which typically happens if one of the clauses has a
default implementation that returns MAX_VALUE if it cannot reason about max
scores.
