match :: Text -> Text -> Maybe Match

match pat s applies the pattern pat to s and returns a Match describing the kind of match if any, or Nothing otherwise. The pattern is interpreted as tokens delimited by whitespace, and each token must be present somewhere in s.

filterMatches :: (a -> Text) -> Text -> [a] -> [a]

filterMatches f pat l returns only those elements of l that match pat, using f to convert each element to a Text. The result will be ordered equivalently to l

sortMatches :: (a -> Text) -> Text -> [a] -> [a]

sortMatches f pat l returns only those elements of l that match pat, using f to convert each element to a Text. The result will be reordered such that exact matches come first, then prefixes, then infixes, although original order will be maintained within these three groups.
