From my experience, I've seen this type of results when your site was previously indexed on google and then your site was down. Rather than deleting you completely from the index, Google is assuming your site is down and because of that it has no information to index you by, so just the url. You'll notice that your site is no longer in the cache (ie:
http://216.239.39.104/search?sourcei...hen-stores.htm) which would be the case if your site is down.
Hope this helps.
