Proper way to handle group for mairix searches?

Proper way to handle group for mairix searches?

Hi all,

I've been using mairix for my mail search recently, because it has the
advantage of rather fast indexing and very fast, yet powerful search. It
functions by copying the matching articles to a folder, for which
various formats are available, with maildir as the default.

So from Gnus point of view, there is a maildir folder that changes its
contents entirely based on the output of mairix.

What I want Gnus to do is to forget about the old status of the folder,
and open it with the new results without checking for new mail or
anything else to slow it down. The best way I found so far was a
combination of

    (gnus-group-quick-select-group 0 mairix-results-group)
    (gnus-summary-reselect-current-group t t)

(see below) but this does not work perfectly. I see zombies in the
Summary and Gnus occasionally seems semi-confused about the group.

Here are my questions:

 a) Can someone tell me how to do this "properly"?

 b) Is there a way to select one of the articles on its Message-ID
    quickly?

Thanks for any help you may be able to provide.

Regards,
Georg

Maybe you can put an IMAP server (Courier/dovecot) in front of the
Maildir?  If not, you may need to write nnmairix based on nnmaildir,
unfortunately (I don't have a better suggestion but someone else may).

Sorry, I haven't done this.

Not currently in core Gnus.  The gnus-registry knows where an article
is, once you visit a group (it notices each article's message ID), but
doesn't remember the article number.  So you can write code that will go
to that group and find the message ID, or you (and I) can extend the
gnus-registry to remember the article number as well.

Having to run an IMAP server to be able to cleanly reread a folder in
Gnus seems a bit excessive, imho.

The registry wouldn't help, because the articles are thrown in by mairix
dynamically. So they are not going through Gnus. What we'd need to do is
enter the group, and then activate the first article that matches a
search in the header fields, I guess, but I'm wondering which would be
the best candidate to use for this.

My best bet right now would be

 (gnus-summary-select-article nil t t
  (car (gnus-find-matching-articles "message-id" msgid)))

to select and display the message with the appropriate id.

Regards,
Georg

Huh?

Is that quick?  I have experienced large delays over IMAP with this
functionality, so I hesitated to recommend it.  Perhaps it's quick with
Maildir sources specifically?

I overlooked "quickly".  This might be not the case for some back
ends.

On nnml it's quite fast.
