Returns a quantity that indicates the greatest similarity concerning the set of trigrams in the initial string and any steady extent of an ordered list of trigrams in the 2nd string. For aspects, see the clarification underneath.

Returns a number that signifies how comparable the two arguments are. The range of the result is zero (indicating the two strings are absolutely dissimilar) to 1 (indicating the two strings are equivalent).

very same 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 greatest similarity between to start with string and any constant extent of text of the next string.

having said that, this purpose does not include padding to your boundaries of your extent. Hence, the volume of extra figures present in the second string is not considered, except for the mismatched word boundaries.
