Returns an array of many of the trigrams from the specified string. (In observe That is seldom practical aside from debugging.)
Returns a selection that implies the best similarity between the list of trigrams in the initial string and any continual extent of an requested set of trigrams in the second string. For facts, see the explanation underneath.
Returns a variety that suggests how related the two arguments are. The array of the result is zero (indicating the two strings are completely dissimilar) to one (indicating that the two strings are similar).
identical as word_similarity, but forces extent boundaries to match phrase boundaries. Since we do not have cross-term trigrams, this perform in fact best289 returns greatest similarity among to start with string and any constant extent of phrases of the 2nd string.
on the other hand, this purpose would not include padding to your boundaries on the extent. Consequently, the quantity of additional figures current in the next string isn't regarded, apart from the mismatched term boundaries.
