Mobile Safari - input field input button

Question

I notice when you go to google.com, for example, the keyboard of the input field has a "send" button, and not the original "return" button.
How to enable this feature? I tried type = search, but I still see the return button.

Thank,
Tee

It really works.
You need to have a form tag, initially I had only an input field.
