It has indexed 5 billion web pages, placed the results on Amazon EC2/S3 and invites you to make use of it for free. All you have to do is setup your own Amazon EC2 Hadoop cluster and pay for the time you use it — accessing the data is free. This idea is to open up the whole area of web search to experiment and innovation. So if you want to challenge Google now you can't use the excuse that you can't afford it."
