dovecot - Jan 2014 - Writing an FTS plugin

Hi, I'm having some trouble writing an FTS plugin that uses notmuch
(http://notmuchmail.org/) as the backend.

As a proof of concept, I'm adding a hardcoded UID to the search results in
the plugin's lookup handler:

  seq_range_array_add(&result->definite_uids, 1, 42);

but this UID is never returned by IMAP SEARCH commands. I know the plugin is
being used, since I'm also syslogging immediately before the call to
seq_range_array_add().

Interestingly, SEARCH commands return correct results (based on the mailbox
content and the search terms specified), but I'm not sure where those
results are coming from. The notmuch plugin is the only configured FTS
plugin:

  mail_plugins = $mail_plugins fts fts_notmuch
  plugin {
    fts = notmuch
  }

What might I be doing wrong?

Additionally, notmuch returns message filenames, which I'll need to
translate to UIDs. I've seen maildir_uidlist_get_uid(), but I'm not sure
where to get the struct maildir_uidlist arg it needs. notmuch only supports
the Maildir format, so using a maildir_* function seems a reasonably safe
assumption, but is there a better way?

I haven't made much progress on this, and I'd love if someone
knowledgeable
about this part of the code base could point me in the right direction.

I'm obv. more than happy to submit the final plugin, but I need a hand
getting past this.
