A bug report: if someone already added “.com” to their results because of no result, don’t offer to add it again if there are still no results.

Example: http://www.privacyparrot.com/search?search=http://www.noSuch...

Also, I suggest when you suggest adding “.com”, you strip spaces from the search as well. For instance, I searched for “Less Wrong” and found nothing, and you suggested “Less Wrong.com”. That doesn’t exist, but “LessWrong.com” does.
