iphone - Mobile Safari - Input field submit button

Question

I notice when you go to google.com for example, the input field keyboard has a "submit" button as opposed to the original "return" button.
How do I turn on that feature?
I tried type=search but I still see the return button.

Thanks,
Tee

Answer 1

It actually works.
Need to have the form tag, I initially only had the input field.
