-@subsection Basic Usage
-
-In the group buffer typing @kbd{G G} will search the group on the
-current line by calling @code{gnus-group-make-nnir-group}. This prompts
-for a query string, creates an ephemeral @code{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 @code{nnir} group made in this way is an @code{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 @emph{warp} to the original group for the article
-on the current line with @kbd{A W}, aka
-@code{gnus-warp-to-article}. Even better, the function
-@code{gnus-summary-refer-thread}, bound by default in summary buffers to
-@kbd{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
-@code{gnus-group-make-nnir-group} (now bound to @kbd{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
-@code{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 @code{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.
