Fuzzy search

A fuzzy search can be used to have a spellcheck. The fuzzy search use Damerau-Levenshtein Distance. To make a fuzzy search just add "~" at the end of the searched term(s).

An optional distance parameter specifies the maximum number of edits allowed, between 0 and 2, defaulting to 2. For example:

test~2
