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.
Also ... do you have access to a college or public library? Even if you go to the library only once to get a library card/number, you should be able to get the usernames and passwords so you can access the huge databases most libraries subscribe to these days. You'll often find better information through them than through general searches on the Internet.
Here is an example -- one college's library website (but public libraries usually have many of these, too): (Broken Link Removed)
Click on Electronic Resources/Databases to see the different databases this particular college provides for its students. EBSCOhost, ProQuest, and Facts.com are among the largest and best.
What does your library provide? That's a good place to research.
