searching for one person's replies in a gnus mailbox only, and not the rest.

[-- Attachment #1: Type: text/plain, Size: 534 bytes --]


Is it possible to search for one particular persons email reply in a
gnus mailbox please? I mean so that only their replies are shown and
no-one else's? Currently when I search for somebodies rely, its
searching through all of the emails displayed, and its showing *all*
the emails in the mailbox with the ones that I'm interested in being
kept in date order along with the rest.

Thanks
Sharon.

That is possible with `gnus-summary-limit-to-author'.
But I have experienced a "limit"ation with that
function, and that is that if I open a group with only
say 20 out of a total of 200 posts/mails, then
`gnus-summary-limit-to-author' will operate on only
those 20!

This might be what some people want but I think it is
confusing, so I wrote this to compensate - with this,
all 200 will be filtered regardless how many was
opened with the group to begin with.

(defun gnus-summary-search-author (author)
  "As `gnus-summary-limit-to-author',
only do this on all articles in the group,
not just those displayed."
  (interactive "sFrom: ")
  (gnus-summary-insert-old-articles t) ; ALL
  (gnus-summary-limit-to-author author) )

Yes, I agree.  I quite often do "/ o / a AUTHOR RET" as a result.

For the OP, the limit to author can also be applied after searching from
the Group buffer using G G.

    / o RET / a AUTHOR RET

OK, but I still like mine better.

I'm not getting any hits with that. Should one mark
groups (with # or `gnus-group-mark-group'), then do
G G and then what do you input as "Query"?

I typically use this on either a single group or a whole topic by simply
placing point on a group or on the topic heading.  For the query, I type
whatever I want, e.g. "Joe Bloggs" (without the quotes) if I want to
search for emails from/about that person.

Indeed, it works simply with point at a group (for
example gmane.emacs.help, without marking it), and
then just:

    G G Eric S Fraga RET

The reason it didn't work earlier was that I tried it
on mail.misc and mail.sent which both use nnml and not
nntp as does Gmane!

Good to know, only optimally, the same should work
transparently for both nnml and nntp, right?

I believe it can be configured to work with nnml. You will need a custom
nnir backend. IIRC namazu and swish(e|++) can both be used here. I used the
former for a time before moving to mairix, which of course offers another
solution to the original question, plus is very fast.

Right -- I think the main point, implicit in Will's answer, is that Gnus
doesn't index or search anything by itself. Nnir is its interface to the
search functionality provided by any given backend. Backends like nnimap
and nntp come with their own search abilities, but nnml is just files on
disk: you need a program to do the searching, then nnir will talk to
that program.

OK, so it should work like this:

    nnml -> nnir -> namazu, or swish(el++)

I'll be back if/when I get it to work...

On Debian:

    sudo aptitude install namazu namazu2-index-tools

Then get this file:

    https://github.com/deftsp/.emacs.d/blob/master/packages/gnus-namazu.el

Gunzip (and restore the .el suffix), then move the
file to `load-path'.

In Emacs:

    (require 'gnus-namazu)
    (setq gnus-secondary-select-methods '((nnml "" (nnir-search-engine namazu))
                                          (nntp "news.gmane.org")
                                          (nntp "news.gwene.org")
                                          (nntp "news.gnus.org")
                                          ))

Then:

    M-x gnus-namazu-create-index RET

(wait)

    M-x gnus-namazu-search <search string> RET

This searches *all* groups, not just the one at point
as with `G G' (which still doesn't work for nnml,
perhaps some setting is still not in effect...)

Have you checked the "will 8.1.3.6 The namazu Engine" section of the
gnus info manual? My guess is you'll still need to set the
`nnir-namazu-remove-prefix' variable. That might be enough, but check
that info page...

Right. The problem was this variable

    nnir-namazu-index-directory

which correctly was/is

    /home/incal/Mail/namazu/

but I had run the indexing command in ~/News/namazu !

In ~/Mail/namazu, after the shell command

    $ mknmz --mailnews ~/Mail/mail/

it works in the Gnus Group buffer with `G G'.

Thanks!
