W10m's search button equivalent in iOS & Android?

[N1cks]

Quick question for those familiar with iOS and Android.

One thing I love about W10m is the magnifying glass search button. Whatever app I'm using, I'm one touch away from search. I use search for everything from spelling, currency conversions, weather.. etc.

What's the equivalent in iOS & Android?

Android is similar, you just hold the center button until Google Now or Assistant (if on 7.0 or 6.0) appears.
On iOS, you can pull down the notification shade and search that way via Spotlight search.

Thanks.

I've since discovered that Cortana can replace Google Now on Android (long press of the home key).

In iOS, a long press of the home key opens Siri? And Siri is powered by Bing.

I have the Bing app by the main home button on my Android phone. Very easy and convenient to use. But like the user before me said you can map Cortana to the home button as well.
