You should use a metasearch engine if you need more results than you would from a regular search engine. You can also use certain metasearch engines like Ixquick or StartPage if you are concerned with privacy. Metasearch engines are usually not search engines themselves. They redirect traffic to actual search engines and then return the results. That can help privacy since the largest search engines record the details of your search. If you use a metasearch engine, then all the large search engines would have is that the metasearch engine performed a search on their sites using whatever terms at whatever time. If the metasearch engine doesn't record your search details, then it would be harder to trace the search back to you.
