Searching for anything and everything on Google is a great, convenient thing—until you lose internet connection. Google remedies this issue by adding offline search to its Search app on Android. It’s starting to roll out to users and it might already be on your device. What offline search offers is it’ll start queuing things you search for when your connection gets spotty. When you get back online, Google will run the search in the background and notify you about search results when they’re ready. To know if you already have this feature, you should see a “Manage searches” option in the slide-out menu. There you will be able to see any pending searches you may have.
