iOS 8 Spotlight Search blank results bug with iPhone 6

Does anyone have a solution or workaround for the Spotlight Search blank results bug in iOS 8? I have an iPhone 6 Plus 128GB running iOS 8.1.1. iOS 8.1.1 was supposed to have fixed the problem, but it hasn't for me. I'm having to power down and restart my iPhone 6+ several times a day in order to get Spotlight Search working properly. Spotlight Search will suddenly stop returning any search results. All I get is a blank screen. After a restart and waiting several minutes for iOS to index, Spotlight Search will return search results including apps. But it's temporary. If I wait an hour and then try to do a Spotlight Search, I get blank search results again. This is really aggravating as I rely on Spotlight Search to launch apps. I've tried going into Settings > General > Spotlight Search, unchecking and checking Apps and other options, hoping that will get search results working without having to restart the iPhone. No luck. I have an iPad Air 2 with iOS 8.1.1. Haven't had any issues with Spotlight Search on the iPad.
