Patrick Marty updated LUCENE-9646:
----------------------------------
Description:
BM25Similarity discountOverlaps parameter is true by default.
It can be set with
{{org.apache.lucene.search.similarities.BM25Similarity#setDiscountOverlaps}}
method.
But this method makes BM25Similarity mutable.
discountOverlaps should be set via the constructor and {{setDiscountOverlaps}}
method should be removed to make BM25Similarity immutable.
