Google’s New Search Index: Caffeine

Google has just announced the completion of a new web indexing system called Caffeine. According to Google, the new web indexing system provides 50% “fresher” results. Fresher?

So why did we build a new search indexing system? Content on the web is blossoming. It’s growing not just in size and numbers but with the advent of video, images, news and real-time updates, the average webpage is richer and more complex. In addition, people’s expectations for search are higher than they used to be. Searchers want to find the latest relevant content and publishers expect to be found the instant they publish.
