Google is bringing a very handy feature to Chrome for Android: auto-suggested answers in the search bar. Right now, however, you'll need to enable an experimental flag to make it happen.
Auto-suggested answers appear while you're typing a Google search query with a definite answer. You can use this feature to get quick answers for questions about basic math problems, weather, and dates for historical events from right within your search bar.
On Android, the auto-suggest answers show up in the drop down menu below what you're typing, along with other auto-suggestions. The number of queries with auto-suggested answers aren't as expansive as the results you get on the desktop when Google auto-loads a search results page before you finish typing. Still, the new feature comes in handy for very specific searches when you're on a smartphone or tablet.
Anyone with a modern Android device should already have Chrome installed. If you don't, you can grab Chrome on Google Play.
Next, type chrome://flags in the address bar. This will open Chrome's flags page with a warning that says "Careful, these experiments may bite." Now, scroll down until you see the heading Answers in suggest towards the bottom of the page.
Tap the button that says Default and select Enabled.
After that you'll be prompted to relaunch Chrome by tapping the button at the bottom of the screen that says Relaunch Now. Do so, and you're ready to go.
In my tests, I found the feature worked best on Android to find the weather with searches like weather [city], and for math problems like the one see in the image at the top of this post. You can also use this feature to find a country's capital city.
Other queries that get quick answers include when did [historical event] and How old is [famous person], according to OMG! Chrome, the site that first reported the new feature.
It's a limited feature at this point, but is still fun to play around with and to have at the ready the next time you want to know what the weather's like in Los Angeles.
