Google has been slowly, very slowly, spreading its App Indexing feature on Android in order to help users discover which Android apps possess content related to what they are looking for. However, that feature had one significant limitation. It only showed results from apps that are already installed on the device. Well, not anymore. Google has just opened up the doors to have indexing work even for apps that are not yet installed on the device, which makes discovery really an act of discovery instead of guesswork.
