Google Caffeine

A new wave for search engines

From PC World

What exactly is Caffeine?

Caffeine is a revamped version of Google's actual search engine -- the code that finds your answers when you type in queries.

How's different Caffeine from the current Google search engine?

The formula itself, in some ways, has changed. Google engineers have actually rewritten parts of the search engine's infrastructure. Of course, Google isn't disclosing exactly what has been altered, but in a nutshell, search results show up faster and in a somewhat different order. The difference may or may not even be noticeable to you.

So is this all happening because of the Microsoft-Yahoo deal?

It's easy to make that conclusion -- after all, it was just days ago that Microsoft and Yahoo announced plans to form a search partnership. Google, though, insists the two events are completely unrelated. "This change has been in the works for months," Google software engineer Matt Cutts assures.
