Google Scholar is an ok tool for research but you'll get better results in less time if you learn how use advanced databases (like those linked on this page). They're not that hard to use and as long as the database is a good match for your topic, you should get better results.
It is most efficient to find resources on your topic by utilizing databases as they contain information about journal articles, book chapters, conference proceedings, meeting reports, and more
Deciding which database to use depends on what you are trying to accomplish. For basic information you can start with a General database. If you need more in-depth information try using one of the subject databases.
