If you wish to resolve such ambiguities when mixing intersections with
other queries you must manually apply groupings.

Note that taking the set difference is *not* commutative. Therefore the
expression: `(b - a) != (a - b)`. For e.g:

    `doge - shiba` will return any doges that aren't shibas. 
    (e.g: the empty set)


    `shiba - doge` will return all your shibas that aren't doge memes.
    (e.g: probably the empty set, unless you really like shibas.)
