For web searches, Safari has a built-in Google search field. It’s near the upper-right corner of the Safari window, and has a magnifying glass icon.
To search the web:
Type a word or phrase in the space next to the magnifying glass. As you type, a list of suggestions based on what you’ve typed so far appears.
Press Return, or click one of the suggestions.
To repeat a previous search:
Click the magnifying glass, and then choose from the menu.
