REMEMBER THE LIMITATIONS OF SEARCH ENGINES
No search engine will find everything available on the Internet, so be sure to use several search engines to find websites that other search engines might not have found. The more search engines you use, the more information you'll find, and the more information you find, the more likely you'll have most of the facts you need to make an intelligent decision.
Sometimes the hardest part about finding an answer is knowing how to look for it in the first place. With so many different search engines available at your fingertips, there's no excuse for not finding the information you want on the Internet right away.
