Google Instant is a search feature that attempts to, in real time, predict what your search query will be, thus saving time. Search terms will appear as gray text in the search box as you type your query. The feature was made available first on PCs, and can be turned on or off.
To activate the feature on your Android 2.2 device, follow Android Central's instrutions:
Just like on the desktop browser, you'll need to go to google.com for this to work (and you'll need to tap the "turn on" link the first time to get it going). Then just start typing your search, and results will appear -- instantly -- below.
Check out the video below from Google to know more about the feature:
Androinica notes that Google Instant "loses some of the appeal because virtual keyboards take up half the screen, leaving very little space to display results as you type."
Disappointed that your device or region isn't supported for Google Instant? Take solace in Google's statement that they are "working to support additional countries and languages and more devices in the coming months, so stay tuned."
