If I have a gnus backend for a local dovecot instance like

                          '(nnimap "mbsync"
                                         (nnimap-address "localhost")
                                         (gnus-search-engine notmuch
                                                             (config-file "/home/me/.notmuch-config")
                                                             (remove-prefix "/home/me/.Maildir/"))
                                         (nnimap-shell-program "MAIL=maildir:$HOME/.Maildir /usr/lib/dovecot/imap")
                                         (nnimap-stream shell))

then Gnus isn't able to translate the filenames returned from notmuch
(e.g. inbox/cur/1615384505.697011_1.laptop,U=5667)
into article numbers. It seems to look up using a function that assumes
you're using nnmaildir:

(if (string-match-p "\\`[[:digit:]]+\\'" article)
			(string-to-number article)
		      (nnmaildir-base-name-to-article-number
		       (substring article 0 (string-match ":" article))
		       group nil))

Here the string-match fails because the filename includes hostname and
U= parts, so we get sent to nnmaildir-base-name-to-article-number which
tries to look up current nnmaildir server which is nil and the end
result is that the computed article number is nil and we get no search
results.

I don't know what the correct way to do this is;
there's https://www.emacswiki.org/emacs/NotMuch#h5o-1 which goes via
message-id's, but maybe there's some better way.

Thanks for the report. Just to be clear, is this something that used to
work before gnus-search landed, and now doesn't? My understanding is
that this part of the code hasn't changed, and this wouldn't have ever
worked, but I'd very much like to know if that's not true.

Basically, there is an ugly bit of heuristics when looking at search
results, and guessing how to handle them. As you've noticed, if the file
name looks like a maildir message, the search code will assume there's
an nnmaildir server involved, and try to find it.

There should be a dedicated method in place to handle a single search
result, which is able to take both the server and the search engine into
account. I've been gnawing on what that might look like, but haven't
implemented it yet.

Eric

I only just tried it now, so I don't know if it worked before.

Okay, no, I don't think this is something that works, nor would it
without some effort. I think it might also just be faster to let your
imap server do the searching itself, if you turn full-text indexing on.

If I understand things correctly, this is something that we're not going
to implement?  So I'm closing this bug report; if I misunderstood,
please respond to the debbugs address and we'll reopen.

No, I don't think this is something we'd expect to implement. IMAP and
notmuch are just two separate systems.
