Quick search apps?

Hi friends.

So I am a recent android convert from ios. I like both, but I'm loving my s7 right now.

Probably the only thing I'm really missing is the quick search bar. I know you can google search quickly, but I want a fast search of my phone. It makes is so much harder easier to pull up the app or email quickly. IPhone has it on the pull down bar, but I was wondering if there's a way to do it that I've yet to find.

Thanks so much.
