You're right, I misremembered the point of that conversation.

I went back and looked at my old work on gnus-search (which will land
someday... sniff), and it looks like I bailed on making this work there,
too. I vaguely remember that I couldn't even make it work properly on
the command line, couldn't figure out why "folder" and "path" returned
the results they did.

But `nnir-run-notmuch' filters its results same as all the other search
routines, so I'm not sure why we can't do the filtering on group name,
after the fact. It has this:

 ;; maybe limit results to matching groups.
 (when (or (not groupspec)
           (string-match groupspec dirnam))
   (nnir-add-result dirnam artno "" prefix server artlist)))))

That should be usable for filtering, right?

I have the feeling that I've gone over all this before, then forgotten
what the conclusion was...
