It's a reasonable mistake to confuse your browser with a search engine because most daily browsing begins with a search. However, whereas a search engine finds Web sites, a browser displays them. Think of the browser as your window to the Web. It doesn't have specific knowledge about the scenery (like a search engine), but you need to look through it to see what's out there.
In addition to displaying Web sites, the browser provides tools to help you navigate among them. Most browsers include many features, like the Bookmarks feature, which helps you keep track of your favorite pages. Successful browsers hide the complex underpinnings of the Web and make surfing pleasurable and easy.
