> 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.
