gnus: Basic Usage
8.1.2 Basic Usage
-----------------
In the group buffer typing ‘G G’ will search the group on the current
line by calling ‘gnus-group-make-nnir-group’. This prompts for a query
string, creates an ephemeral ‘nnir’ group containing the articles that
match this query, and takes you to a summary buffer showing these
articles. Articles may then be read, moved and deleted using the usual
commands.
The ‘nnir’ group made in this way is an ‘ephemeral’ group, and some
changes are not permanent: aside from reading, moving, and deleting, you
can’t act on the original article. But there is an alternative: you can
_warp_ (i.e., jump) to the original group for the article on the current
line with ‘A W’, aka ‘gnus-warp-to-article’. Even better, the function
‘gnus-summary-refer-thread’, bound by default in summary buffers to ‘A
T’, will first warp to the original group before it works its magic and
includes all the articles in the thread. From here you can read, move
and delete articles, but also copy them, alter article marks, whatever.
Go nuts.
You say you want to search more than just the group on the current
line? No problem: just process-mark the groups you want to search. You
want even more? Calling for an nnir search with the cursor on a topic
heading will search all the groups under that heading.
Still not enough? OK, in the server buffer
‘gnus-group-make-nnir-group’ (now bound to ‘G’) will search all groups
from the server on the current line. Too much? Want to ignore certain
groups when searching, like spam groups? Just customize
‘nnir-ignored-newsgroups’.
One more thing: individual search engines may have special search
features. You can access these special features by giving a prefix-arg
to ‘gnus-group-make-nnir-group’. If you are searching multiple groups
with different search engines you will be prompted for the special
search features for each engine separately.
