    what values.

    The mapping is: ``package -> [(key, needle), ... ]``.

        It is not enough to only look at the matches and order them by the sum
        of their weighted hits. In case this number is the same we have to
        ensure that the same matched needles are next to each other in the
        result.

        Returned function is:
        pkg -> (weights_sum, canonized_needles_set, -distance)
