The forum is made up of over 75,000 messages right now, and grows very fast. Currently I'd say it's nearly impossible to do a body search in any reasonable time frame. For our new version of the site (a week or two) there will be an index of the messages that will make it easily searchable. So for now, stick to subject line searches and wait for the new site to go up. Also, you could just ask Joe Offer, and he's likely to know just about anything.
