My iPhone 6 running 9.2 is afflicted with the Spotlight search bug, where I get no results at all. I've tried the various tricks to get it to start working again, and they work, for about 10 minutes, when it stops working again. Does anyone have experience with this issue? I'm wondering if restoring the phone then restoring from an iCloud backup will help at all? No idea the source of this issue and can't find anything online about it. Is it bad settings related? A rouge app? Would love to find a more permanent solution.
