Oh, there's even a gnus-coding.texi in there. I guess I should have
read that before starting to work on nnweb :-)

Hmm, that paragraph about solid groups not being useful seems out of
date, too. Was it written at a time when solid groups weren't backed
up by hash tables, or am I missing something?

   `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 `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 (*note Duplicate
Suppression::) will help, since `nnweb' doesn't even know the
`Message-ID' of the articles before reading them using some search
engines (Google, for instance).  The only possible way to keep track of
which articles you've read is by scoring on the `Date' header--mark all
articles posted before the last date you read the group as read.

I'm more concerned about my English skills than texinfo.

It still doesn't work for me without explicit decoding using
mm-url-use-external + wget. However, it seems to decode fine
implicitly when using internal fetching. I dunno if there is a more
elegant way to solve this than testing for mm-url-use-external. And
wouldn't using external programs nevertheless break or unbreak
depending on the system locale?

Btw, internal url fetching yields a \0d at the end of the buffer,
which makes nnweb-gmane-create-mapping throw an error. I've attached a
patch.

At the moment one could achieve that by customising
nnweb-type-definition:

--8<---------------cut here---------------start------------->8---
(defun my-nnweb-gmane-search-by-date (search)
  (mm-url-insert
   (concat
    (nnweb-definition 'address)
    "?"
    (mm-url-encode-www-form-urlencoded
     `(("query" . ,search)
       ("sort" . "date")
       ("HITSPERPAGE" . ,(number-to-string nnweb-max-hits))))))
  (setq buffer-file-name nil)
  (set-buffer-multibyte t)
  (mm-decode-coding-region (point-min) (point-max) 'utf-8)
  t)

(push '(gmane-by-date
	(article . nnweb-gmane-wash-article)
	(id . "http://gmane.org/view.php?group=%s")
	(reference . identity)
	(map . nnweb-gmane-create-mapping)
	(search . my-nnweb-gmane-search-by-date)
	(address . "http://search.gmane.org/nov.php")
	(identifier . nnweb-gmane-identity))
      nnweb-type-definition)
