As you don't find what you're searching for with a
particular search provider, you can search using a different one. You
can use the Internet Explorer search box to add additional search providers and then switch among them to improve your search results. In Internet Explorer 8 or Google Chrome you can quickly change which search provider to use on a search by clicking the provider's icon below the search box. For Internet Explorer 7, click the arrow next to the search box, and then click a supplier.
