nnweb, gmane search and google groups

[Harry Putnam]

Group,
I've seen recent posts indicating it is possible to do gmane and
google groups searches with gnus.  I haven't done anything like this
since the dejanews days.

Can someone or ones post some examples of how this is done including a
few example search strings?

Gmane doesn't work yet.  But it seems that Andreas already has
prepared a patch for it. :-)

None of that works for me.  Thats why I asked for examples.

I always get an error no matching groups.  Even on known
match strings I mean.
debugger output futher along.

Using gmane I get a bunch of suedo articles that are really all the
links on the lead page of gmane.  Something like:

G w google "example zone files"  returns:
 ( know you said gmane wasn't working yet....) 
  1 . 31-Dec [   0: nobody              ] () 
  1 . 31-Dec [   0: nobody              ] () Home</a><br>
  1 . 31-Dec [   0: nobody              ] () Reading</a><br>

  1 . 31-Dec [   0: nobody              ] () Subscribe</a><br>
[...]

Going to the second hit on nnweb using index search I find a little more
info, in particular:

   You must have the `url' and `W3' package or those alternatives (try
  `customize-group' on the `mm-url' variable group) installed to be able
   to use `nnweb'.

Looking at that I guess I need to toggle it on and set w3m.  I changed
over to w3m a while back for viewing html articles.

Looking up the suggested variable to customize I toggled it on and set
to w3m saved for future.

Now trying nneb I get:
Debugger entered--Lisp error: (error "Couldn't request group: No matching articles")
  signal(error ("Couldn't request group: No matching articles"))
  error("Couldn't request group: %s" "No matching articles")
  gnus-group-read-ephemeral-group("87vevpr3xl.fsf" (nnweb "87vevpr3xl.fsf" (nnweb-search "\"zone files\"") (nnweb-type google) (nnweb-ephemeral-p t)) t (#<buffer *Group*> . group))

Which version of Gnus are trying with? Since the google part has been
fixed only recently, you'll need a version from CVS newer than
2006-02-03 (either trunk or the v5-10-6 branch (AFAIK)). You could
also download the latest version of nnweb.el from here:

<http://quimby.gnus.org/cgi-bin/cvsweb.cgi/gnus/lisp/nnweb.el?rev=HEAD&content-type=text/plain>

...and make sure it gets used instead of the old one.

The fact that you saw some random content of http://gmane.org in the
summary buffer suggests that the http part of your setup is working
correctly.
