It can work outside of all locations, or else in the one location that
handles this request.

So this config can work.

The above rewrite pays no attention to query strings.

So you'll want to do something based on $arg_para -- maybe an "if"
or something involving "map".

I guess (without testing):

if ($arg_para != data) { return 404; }

inside that location{} would probably work.

The above rewrite does that (assuming that the "rewritten" file is absent).

The above rewrite does that; but which html file should it look for here?

/home/www/example/public/doc/one/two/two.html, or
/home/www/example/public/doc/one/two/one/two.html?

(As in: do you repeat everything after /public/doc, or do you repeat
just the final after-slash part?)

With the extra "if" above, I think so.

Your testing should be able to show any problems, or unexpected behaviour.
