Searching the web for under $1000/month
But are you solving the right problem?  This sounds like someone has produced a very good and efficient version of AltaVista.  Back in the 1990s, if you wanted to do classic keyword searches of the web, and find all pages that had terms A and B but not C, it would give them to you, in a big unsorted pile.  The web was still small enough that this was sometimes useful, but until Google came along with tricks to rank pages that are obvious in retrospect, it just wasn't useful for common search terms.
