Do a one finger downward stroke to bring up the search menu. Type an app name "twitter". I expect to see the installed application "twitter" because this is the behavior that occurred in iOS 8. Instead, I see podcasts, mail, messages, notes, websites and bing searches. I have to manually click through my 100+ installed apps to open them or ask siri to do it. This behavior began immediately after upgrading to iOS 9.0.
How do I enable search for installed apps in ios 9?
