Google announced a top secret project called Caffeine yesterday — it’s mostly under-the-hood stuff, so users shouldn’t immediately notice any differences between the old technology and the new.
One of the goals of Caffeine is to index content much faster — that means Google could be trying to figure out real-time relevant search. A better way to search Twitter is probably fairly high on the list — as “Bing” has been dabbling in that as well.
It’s the first step in a process that will let us push the envelope on size, indexing speed, accuracy, comprehensiveness and other dimensions
If you are interested in trying out the new technology, head over to http://www2.sandbox.google.com. Google is looking for feedback, so make sure to submit it using the “Dissatisfied?” link at the bottom, and include the word “caffeine” in your comment.
