If you want Google Chrome to give you instant search results, you can enable this groovy feature that is otherwise turned off. But, this service comes at a high cost to your privacy.
Google Chrome has a feature that lets you bring Google’s instant search to the address bar. By default it’s turned off, and for possible good reason. The Chrome address bar instant search essentially allows Google (or your current search engine) to track everything you type into the address bar. If you’re okay with that, you can enable it. Disabling it is done from the same spot in Chrome settings.
Chrome’s Instant Search
Open up Chrome and click the Wrench >> Settings option.
Scroll down the settings page and click or unclick the Enable Instant for Faster Searching (omnibox input may be logged).
If you’re enabling instant search, Chrome will display an extra confirmation window. This window asserts that your data may be logged if your current default search engine supports this feature. If you agree with it, click OK.
Policy: Any text you type in the address bar is sent to Google so predictions can be retrieved. If you select a prediction from the address bar menu, press Enter, click the search results page that appears, or pause for three seconds with the same text in the address bar, Google logs your text as a search. Otherwise, Google treats the text you typed as partial query data, which is stored for up to two weeks and then deleted.
That’s all there is to enabling or disabling Instant search results in Chrome. If you don’t mind Google or another search engine knowing everything that you type in the address bar, then having it enabled is a rather groovy feature. But if you are more privacy-minded, it is definitely something you’ll want to keep turned off.
