Why not develop a real search engine?

Right now, Google search is a joke and the other search engines are incapable of finding relevant matches, even though the searches can be quite clearly specified and....assuming this is true: it is big, wide, world or internet out there.

Why the f*ck doesn't someone build a real internet search engine?

Rudimentary language understanding is not that complicated - for finding out what people are searching for. But perhaps indexing the web in a meaningful way is not so straightforward. Obviously the whole strategy or promoting the 'popular' must collapse inward under its own weight. We are left not knowing how to find things.

Example: I search for articles on mathematics about language but all Google finds (with minimal exception) is articles on the language of mathematics. Google has not ability to differentiate. All it can do it key-word pair processing through their search tree. And even that is wrong because you add search terms and get more results!
