Returns a number that indicates how related the two arguments are. The variety of the result is zero (indicating that the two strings are totally dissimilar) to one (indicating that the two strings are similar).

identical as word_similarity, but forces extent boundaries to match phrase boundaries. considering the fact that we don't have cross-term trigrams, this perform basically returns finest similarity amongst first string and any continual extent of words and phrases of the 2nd string.

on the other hand, this operate won't increase padding to your boundaries of the extent. Thus, the amount of extra people current in the second string will not be deemed, aside from the mismatched term boundaries.
