Official Google Blog: Google Instant, behind the scenes

Official Google Blog: Google Instant, behind the scenes: "Yesterday we introduced Google Instant, a change to make search fast and interactive by showing you results instantly as you type. With Instant we’ve turned search from a static HTML page into an AJAX application, just as we did with Google Maps and Gmail. You can learn more about Google Instant in yesterday’s blog post, but we also wanted to share a peek behind the scenes into some of the engineering challenges we faced in design and infrastructure."
