Some months ago I created a minimalistic app for searching within Facebook groups. You can try it at http://gs.sullof.com. Currently, GroupSearcher injects a bit of code in group walls and works very well. But not always. In fact, if you add a note to the group, it's impossible to find it because Facebook doesn't return notes in the group stream. I contacted Facebook in all possible ways but I received no answers. Also Quora didn't helped me. Probably, I should try with StackOverflow.<p>Is there someone that knows how to obtain notes in a group stream using Facebook Query Language?
