not a string, so you can't use %:query although you can access it from
Emacs Lisp embedded in the template.

I don't have any secret knowledge, I just dug through the source code
and experimented with different inputs.

Of course :) It's a bit difficult skimming through the code as I don't have org-protocol set up.
 
The code and/or documentation could be clearer

Would you like to submit a patch for that?
