"Google Chrome will add support for instant search, the feature released this week by Google. An early implementation is already available in Chrome Dev Channel and in Chrome Canary build. You can enable this feature by adding the following command-line flag to a Chrome shortcut: —enable-match-preview (in Windows, right-click on the shortcut, select “Properties” and append the flag to the “Target” value)."

Instant search no Google Chrome, já está disponível no dev channel.
