A better search engine?

Hi all,
I'd like to ask your opinions, since you are the most tech-savvy people I know! One of my colleagues in my dept is a computational linguist, and he is a collaborator on a new search engine which he says is better than Google. The idea is that the search is based not on key words but on the *meanings* of actual phrases and sentences. The beta version is at:

Could you guys check it out and tell me what you think? They are still developing it but the real version is supposed to appear later in the year.

Here is a video of my colleague talking about the theory behind it (click on the second video from the top):
