Here's something that may work.  The main problem is that it takes
time to read the entire message, since Gnus doesn't do partial
retrievals, so for large messages it's slow.  This is especially bad
with nnimap, because you have to use a network connection to retrieve
the message.

This function grabs the first 10 characters in the article body.  You
may want to extract words in some other way, it's up to you.  Also if
there aren't 10 characters available you may get an error - a regular
expression is probably the best way to work this.

(defun gnus-user-format-function-B (headers)
  (if (and headers gnus-newsgroup-name)
      (let* ((article (spam-fetch-field-fast -4332 'number headers))) ; -4332 is a fake article number
	(with-temp-buffer
	  (gnus-request-article-this-buffer
	   article
	   gnus-newsgroup-name)
	  (article-goto-body)
	  (buffer-substring-no-properties (point) (+ (point) 10))))
	"--invalid headers or group name--"))

If you use this function or something like it, just put %uB in your
summary format string.
