In most modern browsers the address bar is also the search bar, so effectively the search bar takes up zero room. If you configure your address bar search properties to use google, then you won't need to go to the google site.
Perhaps ivor4781 you will explain what you mean by a search bar. Is it the narrow box alongside the address box, in the Tool bar section at top of page.
you ask why people need a search bar...the clue is in the word search
then you tell us you dont use them and havent for 15 years because it takes up screen space ....
