[讨论]how do you feel to add a inner searching enging?

When i need some techinical or quality material, i always come here, but what make me confused is that it is too difficult to find what i need. so i suggest to insert a searching enging to the frontpage. how do you feel about it? waiting for your surpport! if we feel it is very useful, i believe the owner of the website will try. yes?? :)
