Query strings arguments are just strings. Whatever encoding you layer
on top of those strings, in order to be able to treat them as arrays,
is entirely subjective: you could be using any one of a number of
encodings. Nginx has no mechanism to deal with this in its vanilla
setup, as far as I'm aware.

I don't know how its embedded perl or lua modules might be /able/ to
treat them, but you'd almost certainly have to /train/ them (at least
trivially) in how to understand your specific encoding: semi-colon
separated? Brackets of some kind? Some more densely packed binary
encoding which you've then had to base64 encode because of HTTP? Nginx
doesn't know this, and doesn't give you this functionality out of the
box.
