Same as word_similarity, but forces extent boundaries to match term boundaries. given that we do not have cross-word trigrams, this operate actually returns finest similarity in between initial string and any steady extent of text of the 2nd string.
having said that, this operate will not insert padding on the boundaries of the extent. Therefore, the number of supplemental figures existing in the second string is not considered, apart from the mismatched phrase boundaries.
