We wrote about Google’s Quick Search Box (QSB) a few months ago when the product was officially launched. We found the Twitter plug-in particularly interesting because QSB was able to turn into a Twitter app that let you post Tweets from the search box itself. Now, Google is launching a version of QSB for the Android Phone which provides similar functionality from the phone’s home screen.

QSB on the Android aims to cut down on keystrokes by providing suggestions as you type and provides a single search box to let you search a variety pf content on your phone, including apps, contacts, and browser history, as well as content from the web, like personalized search suggestions, local business listings, stock quotes, weather, and flight status. And QSB is intuitive; the search box will pull up items that you search for and use most often.

On of the most compelling features of QSB for the Andoid is that third-party developers can include suggestions in search, letting outside information from any apps make into searchable content. So if the app is built with QSB support, QSB will index the content in the app and it will show up in the box. For example, you could search a Twitter app for Tweets.

Unfortunately, it doesn’t appear that QSB for the Android has the ability to Tweet from the search box itself, but perhaps that plug-in will be added in the near future.
