What kind of search do we need?

I was thinking about how could google search can be improved.... Many of us familiar with semantic search. I am thinking about user sourced semantic search, yes this is, for sure, my idea. I was thinking this from long back. Probably knotting multiple familiar technologies and drawing similarities to them and come up with something. It is like GOF came up with design pattern or Ward Cunningham influenced Design pattern which he got influenced from Alexander (Civil Architect). I will explain how.... here you go...

People do search and click on the link... if they didn't find the relevant information they move on and to next page or try to refit the query. So here is the catch. If the move on and click any link, it means earlier page had just noicy result that should be eliminated. Is it correct it does in the first attempt? No, don't trust single person. From my young age if I want to ask a route to some place, which I like to go, I normally ask more than a person.

There are 2 reasons,

1. person who answered could have lied

2. Double check will make sure that probability of error reduced. So if both person points two different directions, you need to be very careful. Ask few more....

So this is thingy I developed when I was young.

So why can't it be applied to search?
