Yes, notmuch works, at least for nnml in my case.  You have to create
and update the search database using "notmuch new" periodically outside
gnus.  I use crontab for this.

Within gnus, you have to do something along these lines:

#+begin_src emacs-lisp
  (require 'nnir)
  (push '(nnml . notmuch) nnir-method-default-engines)
  ;; the following turns off new behaviour that limited search to specific 
groups
  (setq nnir-notmuch-filter-group-names-function nil)
#+end_src 

Finally, you may have to define appropriate settings (e.g. the database)
in your ~/.notmuch-config configuration file.

HTH,
