    By default, the comparison is also ordering dependent. If ``qs`` doesn't

    provide an implicit ordering, you can set the ``ordered`` parameter to

    ``False``, which turns the comparison into a Python set comparison.

    ``False``, which turns the comparison into a ``collections.Counter`` comparison.

    If the order is undefined (if the given ``qs`` isn't ordered and the

    comparison is against more than one ordered values), a ``ValueError`` is

    raised.
