partialRatio
partialRatio(
a,b):number
Compute the partial ratio between two strings.
Lower-cases both strings and collapses whitespace runs into single
spaces, then compares the shorter string with every window of the same
length in the longer one and returns the highest normalized Levenshtein
similarity. Useful when one string is a substring or truncation of the
other; it does not match abbreviations (MSFT vs Microsoft scores low).
Scores can differ from fuzzball’s / RapidFuzz’s partial_ratio, which
use a different alignment. Returns a value between 0.0 and 1.0.
Takes time proportional to the length of the longer string times the square of the length of the shorter one: about 0.4 s for a 1,000-character string against a 10,000-character one with the native addon.
