The ‘search field’ is called an address bar combined with predefined search engines in my browser and accessible at all times using C-x f d without fiddling around with site-defined search entry fields. Oh, and it’s much smaller and takes up space anyhow…
It's entirely possible for someone to use multiple search engines that aren't already predefined. Step outside of your power-user mindset for a second and realize there are "normal" people in this world, unlike you and I, who don't know VIM keybindings or what predefined search engines are and just want to play around with a new search engine.
