The first thing will be to get the (config-file "file") bits inside the
search engine config, like so:

(nnmaildir "gmail" (directory "~/mail/gmail")
           (gnus-search-engine gnus-search-notmuch
             (config-file "/home/alex/.notmuch-config")
             (remove-prefix "~/mail/gmail"))
           (get-new-mail nil))

Note that you'll also need a remove-prefix setting for each engine, also
inside the gnus-search-engine sexp. That's a required setting, so I'll
add it to the example in the search section of the manual, it's
confusing to not have it in there.

Try with updated config as above, and let me know if that fixes it.
