"swish++ -- A Mail Indexing System for Humans"
* swish++ + Email
Swish++ is great for indexing and later, of course, searching and
retrieving your old emails.
!!! Swish++ searches on a per file basis, so its use only makes sense
with one-file-per-message systems (like Maildir, gnus nnml, mh ... and
not with mbox based storage -- use grepmail instead or just switch
your mail system, especially with a high volume of archived messages)
** Indexing of emails
swish++ provides a specific module for this purpose
*** index example:
pwd = ~/Mail
index++ -v3 -s stop_words -e 'mail:*' -E 'Incomin*' -E '*~'
./archive ./Ich ./drafts ./maintainer ./maintainer-debian
-e denotes the module, -E excludes file-pattern and -s indicates a
specific stop word file
(man index++)
*** cron
If you want always "fresh" indexes you need the help of cron.
**** cron sample
41 06 * * * /usr/bin/index++ -s /home/YOU/Mail/stop_words -e 'mail:*' -E \
'Incomin*' -E '*~' -E '*.alt' \
--config-file=/home/YOU/Mail/swish++.config \
--index-file=/home/YOU/Mail/swish++.index /home/YOU/Mail/archive /home/YOU/Mail/Ich /home/YOU/Mail/drafts /home/YOU/Mail/maintainer 2>&1
"Index every day at 6:41 the mentioned directories (recursively - the
default) use a config-file and create the index in /home/YOU/Mail; use
the mail module (-e 'mail:*') and don't index certain patterns (-E
...)."
Or put the whole command as a script and execute it from cron:
41 06 * * * /home/YOU/cron_swish++.sh 2>&1
*** search example:
>search++ from = mhummel and swish
# results: 9

Though this is already quite useful, it doesn't signify the whole
comfort. I bet you want to read the rediscovered email with your
favorite mail reader.
(for search++ options s. man search++ , of course)
* Mail Reader Integration of swish++
** Integration with emacs + gnus + nnir
*** How to use emacs?
Get one year of vacancy and have some kind of remote approach to this digital
epos.
*** How to use gnus?
See above ...
*** gnus + nnir + swish++
In the examples directory you'll find a patched version of nnir.el
(Maybe the small patch will be included at the time you are reading
this.)
**** nnml-back-ends and nnir
***** put nnir.el in your load-path
***** Add the following to your ~/.gnus init-file
(setq nnir-search-engine 'swish++)
;;the following are the default values
(setq nnir-swish++-program "search++") ; the search executable in Debian
;(setq nnir-swish++-index-file "/home/YOU/Mail/swish++.index");
;the index location mail is stored in ~/Mail normally -- the default
(Have a look at Kai's commentaries in nnir.el
Maybe you have to set 'nnir-mail-back-end' but with nnml -- and
having nnml as the default gnus-select-method -- the default is
fine)
***** Interaction within gnus
Type G G and you will be prompted for a query (enter the same as with plain
search++ at the command line).
The search results will form a new group.
Further try G T and enjoy
** Integration with mutt
mutt supports the Maildir format and mh
(http://www.reedmedia.net/misc/mail/mailbox-formats.html and
http://www.courier-mta.org/mbox-vs-maildir/#intro1) well; you don't
need to install qmail to be able to work with maildirs, not even
the MTA needs maildir support s. procmail (even Mail::Audit does
the right thing, discovering a maildir, and accepts to the
Maildir/new directory).
*** swishmutt.sh
(Caveat: You need the procmail package installed -- for the mbox
formatter)
Copy this script to your ~/bin/ directory (or, of course adapt the
settings to your needs)
It's just an example of how you could parse the swish++ results
for mutt. But checking and adapting the variables it should
work out of the box.
Add something like:
macro index "\ch" "!~/bin/swishmutt.sh\nc=sqmbox.tmp\n"
folder-hook sqmbox.tmp set sort=mailbox-order
to your .muttrc file. (Make sure that mutt actually finds the
temporary mbox : sqmbox.tmp -- the script assumes
~/mail/sqmbox.tmp)
The folder-hook is necessary to conserve the search ranking. (The
mailbox order is OK, so no mess with date_sent and the like.)
**** Interaction within mutt
The macro works from within a mail folder. Just press Ctrl-h and
you will be prompted for a query.
Then if everything works fine you will enter a temporary mbox
with the emails ordered corresponding with the search++ results.
