        ----------

        allow_partial_matches: (Optional) If `True`, then only some of the tokens in a value need to exist to
         be considered
        a match. The default value is `False`.

        locale: (Optional) locale/culture code of the utterance. Default is `en-US`.

        max_token_distance: (Optional) maximum tokens allowed between two matched tokens in the utterance. So with
        a max distance of 2 the value "second last" would match the utterance "second from the last"
        but it wouldn't match "Wait a second. That's not the last one is it?".
        The default value is "2".

        tokenizer: (Optional) Tokenizer to use when parsing the utterance and values being recognized.
