Search Engine

[Scientist]

I don't want a complete copy of Yahoo or Google, but wheres a good search engine to make of you're own?

With little hassle on understanding.

To build a search engine like either yahoo or google would take a massive amount of computing resources as they both search and index millions of webpages from millions of websites hosted around the world.
