Google announced the completion of their new web indexing system dubbed Caffeine.
Caffeine provides 50% fresher results for web searches than Google's last index, and it's the largest collection of web content Google has 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. Let's test this! In the headline of this story is a unique word Google's index never heard about.
I will search for the term as soon as the story is published and update the story with how fast Google indexes it.
Update: It took over a minute before this page was searchable with the term "Cyberreblaus". Twitter had indexed the story faster than Google, but of course Twitter just has to deal with the short title. From an end user perspective the Caffeine is still not the real time web, but close enough.
Google says that very second Caffeine processes hundreds of thousands of pages in parallel. If this were a pile of paper it would grow three miles taller every second.
Caffeine takes up nearly 100 million GB of storage in one database and adds new information at a rate of hundreds of thousands of gigabytes per day. Via this Google post.
