nnir sort of caches its results -- if the group hasn't been killed
between searches, you'll just see the same results again. nnir doesn't
support re-scanning, otherwise it seems like it would be reasonable to
use M-g in an nnir group to refresh the results. I don't know if it's
possible to implement `nnir-request-scan', or if it simply won't work
for any ephemeral groups.

To be honest, I just did a little testing, and I couldn't even get marks
to propagate: I flagged a message (the "real" backend was nnimap),
exited the group, and the flag wasn't there in the real group, nor in
the nnir group when I re-ran the search.

Sorry I don't have anything more helpful!
