Tap to search

I was wondering if it would be possibile to add "tap to search" functionality so that when i search an item insted of clicking the search icon on the keyboard i'd click on the suggestion.
Also i was wondering how to add a drop shadow to the search bar that'be awesome!

Thank you for the work you've done, it's truly fantastic!

Start by locating the Android search suggestion handling and the search bar styling entry points. Clarify whether tapping a suggestion should submit the search, and define the desired drop-shadow appearance; done means both requested interactions and the visual change are implemented and verified.
