Is it possible to do a wildcard search in spotlight in iOS 10.X? I want to search for a specific app (example of Instaflash) on my iPhone or iPad but only remember part of its name. In this example 'flash' being the search term inputted into spotlight in iOS 10.X on my iPhone or iPad. Can search terms somehow be used with a wild card option? Something like flash to obtain a list of possible results?
They don't do wildcards, but flash would bring up anything that contains flash including flash at the beginning, end or middle of the word.  If you are talking about mid-wildcards like fl***light, then no, you cannot do that.
