My favorite way to search is to go to Google's advanced search page http://www.google.com/advanced_search?hl=en and put my search words or phrases into the first or second search box (either "all the words" or "exact phrase"). Another is to start out at http://scholar.google.com. However, there many other strategies for searching you can use, and the HOW TO SEARCH THE INTERNET section will help you best.
