Hi,

I want to introduce a *mathematical* search engine working over English Wikipedia dump. The key advantage is simple - *it works* ;).
Better than a nice speech is a real demo which can be found here:

If you are somehow interested or just want to share your thoughts do not hesitate to contact me.

Best regards,
Jozef Misutka
