Returns an array of every one of the trigrams within the supplied string. (In practice This can be seldom handy except for debugging.)
Returns a amount that implies the greatest similarity amongst the list of trigrams in the initial string and any ongoing extent of the requested set of trigrams in the second string. For facts, see the explanation underneath.
Returns a quantity that signifies how related the two arguments are. The range of The end result is zero (indicating which the two strings are completely dissimilar) to one (indicating the two strings are similar).
similar as word_similarity, but forces extent boundaries to match term boundaries. due to the fact we don't have cross-word trigrams, this function truly returns best similarity between very first string and any constant extent of words and phrases of the 2nd string.
on the other hand, this function will not increase padding towards the boundaries in the extent. Consequently, the amount of further figures existing in the 2nd string is not really regarded as, aside from the mismatched word boundaries.
