I am implementing a search bar on a mobile device (smartphone) in which I start with only a search icon button, but when the user presses it a text field becomes notice-able next to this icon and a keyboard pop-ups. This way I hope that there is some extra attention on the search icon and lets the user explore what it does.
My question is about this search icon, most UI's have their search field at the top of the screen, which also leaves space for recommendations of possible related searches beneath. However most mobile users are right handed and it's a lot easier to press the lower end of the screen than it is the top. So it makes sense to put a button like this at the bottom of the screen, like can be seen in the material design with a button in the corner right.
This however has problems of its own, you could have two search buttons, at the bottom and top and separate the search icon from the search field which separates these coherent tools in the layout. I find this somewhat problematic.
Is there any better solution to this? I need to have a search bar with suggestions that's extremely quick to use not like I see it in smartphones today with the search bar at the top. The main functionality is searching of the application.
