Google has announced that it has finally completed its new web indexing system, Caffeine, and thats it’s now live worldwide. It’s taken them almost a year, but what has been said about the improvements the new Caffeine index sounds promising.

They also claim that it gives 50% fresher search results for web search than the previous index and that it has more web content than its ever offered before. Carrie Grimes, a Google software engineer has stated, “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.”

On the subject of content, Grimes also adds, “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.”

Google says Caffeine analyses the entire web in small portions to update the search index on a simultaneous and continuos basis, and this is done worldwide. When new pages and updates to existing pages are added to the index straight away, thereby increasing freshness. Caffeine takes up around 100,000 TB (1 TB = 1024 GB)

The first mention of Caffeine was at SES San Jose just under a year ago, and with more events going on you can expect to hear much more from Google about Caffeine very soon.
