Returns a range that implies the best similarity amongst the set of trigrams in the first string and any ongoing extent of an purchased list of trigrams in the next string. For facts, begin to see the clarification underneath.
Returns a amount that suggests how related the two arguments are. The choice of the result is zero (indicating the two strings are wholly dissimilar) to at least one (indicating which the two strings are equivalent).
similar as word_similarity, but forces extent boundaries to match word boundaries. given that we do not have cross-word trigrams, this perform actually returns finest similarity among 1st string and any continuous extent of phrases of the next string.
nonetheless, this purpose does not incorporate padding to your boundaries of your extent. Thus, the number of further characters existing in the next string is not really considered, except for the mismatched term boundaries.
