My first impression: you can now get useful results after typing a few characters. Google has never been so fast.
To watch a webcast of Google's search event where streaming search will be launched, visit youtube.com/google.
Update: The feature is called Google Instant. "Feelings of euphoria and weightlessness are normal. Do not be alarmed."
"Google Instant is a new search enhancement that shows results as you type. We are pushing the limits of our technology and infrastructure to help you get better search results, faster. The most obvious change is that you get to the right content much faster than before because you don’t have to finish typing your full search term, or even press 'search.' Another shift is that seeing results as you type helps you formulate a better search term by providing instant feedback. You can now adapt your search on the fly until the results match exactly what you want. In time, we may wonder how search ever worked in any other way."
