Hi, I was looking at Lucene's code for MoreLikeThis, specifically this line: https://github.com/apache/lucene/blob/69b040fc6292ac47d7f7fc8bc3b7fd601794e54b/lucene/queries/src/java/org/apache/lucene/queries/mlt/MoreLikeThis.java#L640
It looks like in ClassicSimilarity, TF is a square root, but in the code TF is used without the ClassicSimilarity::tf() function called. Is that a bug - it will make TF have a disproportionately higher weight compared to IDF? --Petko
