Google announced it switched to Caffeine, a new search indexing technology the company has been testing since August 2009. The search giant promises Caffeine will index new web content faster than ever before, and states Caffeine is a robust foundation that makes it possible to build an even faster and comprehensive search engine that scales with the growth of online information.
Today, we're announcing the completion of a new web indexing system called Caffeine. Caffeine provides 50 percent fresher results for web searches than our last index, and it's the largest collection of web content we've offered. Whether it's a news story, a blog or a forum post, you can now find links to relevant content much sooner after it is published than was possible ever before.
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.
To keep up with the evolution of the web and to meet rising user expectations, we've built Caffeine.
