How Caffeine Is Giving Google a Turbo Boost

Google's revamped its search indexing methodology earlier this week. Google late June 9 announced that its search engine was now running on "Caffeine," meaning search results would show more recent information posted on the web as the technology behind it indexes results in seconds rather than weeks. But the allure of Caffeine isn't just the actual real-time search engine, it's the secret infrastructure sauce that Google uses to make a continuing real-time index of the entire web possible. That technology involves custom-built hardware and software that plenty of startups or business analytics companies would love to get their hands on.
