How can I include the article text/body in the RSS feed of the wiki updates section?

Question

I recently migrated from Snow Leopard Server to Lion Server.  Largely, because some people had trouble accessing via their PC under SLS.
Our primary tool is the wiki. 
In Snow Leopard Server, we could generate an RSS feed for specific saved searches or recent changes/updates, adjust article length in the RSS feed, etc.  Using a feed burner, like Feed My Inbox, we were able to have a daily digest "emailed" to a mailing list.  Whereby, we'd get an email of any wiki articles that had changed, along with text from the body, so we can see the changes to the article in the email.
With Lion Server, the only RSS "feed" we can find appears to be on the Updates page.  Which is fine. Are there others?
Second, the we can't seem to change the article "length" at all.  All we see on the Updates feed is the title, change date, who made the change.  We used to be able to see a few sentences of the article body/text for each article...not just the title, but some of the changes.
Of course, our feed burner, now only sends along the article title in the digest...no text beyond that.
We've used the built in push notification in Lion Server, but again, that sends a nice email saying Wiki Article Title "X" has been modified by User "Y" with the date/time stamp.  You can click the link to read more, but no article /body is sent.
Is there a way to generate an RSS feed/link that shows not just the recent updated titles, but the first few lines of text in the article body itself in the index/summary?
I appear to be missing an easy way to generate RSS feeds, based on search criteria.  And changing the article length in the sidebar, to max, never seems to show any of the wiki article.
How can I show a portion of the wiki article body/text underneath the title of the article in the RSS feed in Lion Server?  Not just the article title and changed date?

About a month ago, I spend zillion hours to migrate from Eudora to Mail.
Eudora has been wonderful to me since Day 1 back in the early 90's. But, it has been discontinued as a commercial product. I had used the Japanese version of Eudora for several years, but it did not like communicating with Exchange at work.
I tried and tried various email clients before settling on Mail.
When I pictured interactions among my Mac, iPhone, and whatever email client I choose, Mail was just the simplest way. But, Mail is not Eudora. And, I dearly miss Eudora.
If there is no way to alter the contents of received email in Mail, I would have to adopt your approach on a case-by-case basis.
Thanks for your help, though.
