+@cindex searching the Usenet
+
+It's, like, too neat to search the Usenet for articles that match a
+string, but it, like, totally @emph{sucks}, like, totally, to use one of
+those, like, Web browsers, and you, like, have to, rilly, like, look at
+the commercials, so, like, with Gnus you can do @emph{rad}, rilly,
+searches without having to use a browser.
+
+The @code{nnweb} backend allows an easy interface to the mighty search
+engine. You create an @code{nnweb} group, enter a search pattern, and
+then enter the group and read the articles like you would any normal
+group. The @kbd{G n} command in the group buffer (@pxref{Foreign
+Groups}) will do this in an easy-to-use fashion.
+
+@code{nnweb} groups don't really lend themselves to being solid
+groups---they have a very fleeting idea of article numbers. In fact,
+each time you enter an @code{nnweb} group (not even changing the search
+pattern), you are likely to get the articles ordered in a different
+manner. Not even using duplicate suppression (@code{Duplicate
+Suppression}) will help, since @code{nnweb} doesn't even know the
+@code{Message-ID} of the articles before reading them using some search
+engines (DejaNews, for instance). The only possible way to keep track
+of which articles you've read is by scoring on the @code{Date}
+header---mark all articles that were posted before the last date you
+read the group as read.
+
+If the search engine changes its output substantially, @code{nnweb}
+won't be able to parse it and will fail. One could hardly fault the Web
+providers if they were to do this---their @emph{raison d'etre} is to
+make money off of advertisements, not to provide services to the
+community. Since @code{nnweb} washes the ads off all the articles, one
+might think that the providers might be somewhat miffed. We'll see.
