- then you only have to set either the tick or the dormant
- mark for articles you want to keep, setting the read
- mark will remove them from cache.

-@subsubheading Question 6.3:
-
- How to search for a specific message?
-
-
-Answer:
-
- There are several ways for this, too. For a posting from
- a Usenet group the easiest solution is probably to ask
- @uref{http://groups.google.com,groups.google.com},
- if you found the posting there, tell Google to display
- the raw message, look for the message-id, and say
- @samp{M-^ the@@message.id RET} in a
- summary buffer.
- Since Gnus 5.10 there's also a Gnus interface for
- groups.google.com which you can call with
- @samp{G W}) in group buffer.
-
-
- Another idea which works for both mail and news groups
- is to enter the group where the message you are
- searching is and use the standard Emacs search
- @samp{C-s}, it's smart enough to look at
- articles in collapsed threads, too. If you want to
- search bodies, too try @samp{M-s}
- instead. Further on there are the
- gnus-summary-limit-to-foo functions, which can help you,
- too.
-
-
- Of course you can also use grep to search through your
- local mail, but this is both slow for big archives and
- inconvenient since you are not displaying the found mail
- in Gnus. Here comes nnir into action. Nnir is a front end
- to search engines like swish-e or swish++ and
- others. You index your mail with one of those search
- engines and with the help of nnir you can search trough
- the indexed mail and generate a temporary group with all
- messages which met your search criteria. If this sound
- cool to you get nnir.el from the contrib directory of the Gnus
- distribution or
- @uref{http://quimby.gnus.org/cgi-bin/cvsweb.cgi/~checkout~/gnus/contrib/nnir.el?rev=HEAD&content-type=text/plain}
- Instructions on how to use it are at the top of the file.

-@subsubheading Question 6.4:
-
- How to get rid of old unwanted mail?
-
-
-Answer:
-
- You can of course just mark the mail you don't need
- anymore by saying @samp{#} with point
- over the mail and then say @samp{B DEL}
- to get rid of them forever. You could also instead of
- actually deleting them, send them to a junk-group by
- saying @samp{B m nnml:trash-bin} which
- you clear from time to time, but both are not the intended
- way in Gnus.
-
-
- In Gnus, we let mail expire like news expires on a news
- server. That means you tell Gnus the message is
- expirable (you tell Gnus "I don't need this mail
- anymore") by saying @samp{E} with point
- over the mail in summary buffer. Now when you leave the
- group, Gnus looks at all messages which you marked as
- expirable before and if they are old enough (default is
- older than a week) they are deleted.

-@subsubheading Question 6.5:
-
- I want that all read messages are expired (at least in
- some groups). How to do it?
-
-
-Answer:
-
- If you want all read messages to be expired (e.g. in
- mailing lists where there's an online archive), you've
- got two choices: auto-expire and
- total-expire. Auto-expire means, that every article
- which has no marks set and is selected for reading is
- marked as expirable, Gnus hits @samp{E}
- for you every time you read a message. Total-expire
- follows a slightly different approach, here all article
- where the read mark is set are expirable.
-
-
- To activate auto-expire, include auto-expire in the
- Group parameters for the group. (Hit @samp{G
- c} in summary buffer with point over the
- group to change group parameters). For total-expire add
- total-expire to the group-parameters.
-
-
- Which method you choose is merely a matter of taste:
- Auto-expire is faster, but it doesn't play together with
- Adaptive Scoring, so if you want to use this feature,
- you should use total-expire.
-
-
- If you want a message to be excluded from expiration in
- a group where total or auto expire is active, set either
- tick (hit @samp{u}) or dormant mark (hit
- @samp{u}), when you use auto-expire, you
- can also set the read mark (hit
- @samp{d}).
