Could Cache Optimization Boost Search Engine Speed by 25%?

[zankaon]

Might a road to significantly faster search engines (25% faster) be via use of a cache of say the 100,000 most frequent search words and phrases utilized, typical for over a year? Might one have perhaps a number of distributive caches for a multitude of different processors and associated memories?

I think that's probably already done. Google has a statistics page where it shows the most common words searched of the day. It doesn't really feel like there needs to be much of a speed increase. Anything I type in seems to be pretty much instant.

I wouldn't mind an auto-fill feature like the "suggestion" dropdown when searching using the top right bar in firefox. (having that on the main page)
