Returns a quantity that signifies how similar the two arguments are. The selection of the result is zero (indicating that the two strings are absolutely dissimilar) to one (indicating the two strings are identical).
Same as word_similarity, but forces extent boundaries to match phrase boundaries. given that we don't have cross-term trigrams, this perform actually returns finest similarity concerning first string and any constant extent of text of the next string.
having said that, this purpose will not incorporate padding for the boundaries in the extent. Thus, the amount of further characters current in the next string isn't regarded as, apart from the mismatched phrase boundaries.
