Hello.
The explanation of https://lucene.apache.org/core/8_0_0/core/org/apache/lucene/search/PhraseQuery.html#getSlop <https://lucene.apache.org/core/8_0_0/core/org/apache/lucene/search/PhraseQuery.html#getSlop--> writes that the edit distance between "quick fox" and "the fox is quick" would be at an edit distance of 3; this seems inaccurate to me. I don't know if the edit distance used by Lucene is the Levenshtein distance (insertion, deletion, substitution, all of weight 1) - a standard in information retrieval - but a test of "quick fox" PhraseQuery with a slop of 2 hits the text "the fox is quick" (1 deletion + 1 insertion); the slop does not have to be 3. I wonder if I'm right.
