Thank you for the response.

I setup my mu with the following configuration:

--8<---------------cut here---------------start------------->8---
  (gnus-secondary-select-methods
   '((nnmaildir "@alshehhi.io"
                (gnus-search-engine gnus-search-mu)
                (directory "/home/husain/.nnmaildir")
                (config-directory "/home/husain/.cache/mu"))))
--8<---------------cut here---------------end--------------->8---

I evaluated the code you provided (with debug enabled). Now when I hover
over a group and hit G G and type the string 'hi', I get the following
error:

    Group nnselect:nnselect-87zfhsdwjp.fsf contains no messages

However, when I run

    $ mu --debug find 'hi' --muhome=3D/home/husain/.cache/mu --format=3Dpla=
in --fields=3Dl

I do get results. Here is mu logs:

    # logs from running the mu command from the cli

They are both identical. I suspect that mu is returning a response to
gnus, but gnus fails to display them. If you have any suggestions on how
to fix this, I very much appreciate it.
