Guess what? Google is launching a new version of its search technology known as Google Caffeine. It was first unveiled back in August this year. This improvement doesn't change the interface, design but instead it provides us with better search accuracy and fast indexing speeds.
Google said that Caffeine would launch soon in a new data center.
Here's what Google wrote on their Caffeine splash page:
We appreciate all the feedback from people who searched on our Caffeine sandbox.
Based on the success we've seen, we believe Caffeine is ready for a larger audience. Soon we will activate Caffeine more widely, beginning with one data center. This sandbox is no longer necessary and has been retired, but we appreciate the testing and positive input that webmasters and publishers have given.
I gave it a go during it's beta stages and though I did notice some difference in the search results, the search queries timings also appear much lower.
