Returns a fuzziness object with maximum levenshtein distance in auto mode.
Generates an edit distance based on the length of the term. Low and high distance arguments may be optionally provided AUTO:[low],[high]. If not specified, the default values are 3 and 6, equivalent to AUTO:3,6 that make for lengths: 0..2 Must match exactly 3..5 One edit allowed >5 Two edits allowed AUTO should generally be the preferred value for fuzziness.
