Break up your search into its smallest parts. Ex: instead of searching for "gender differences in media use" search for media use AND gender
Think about other ways that an author might describe your topic. Articles gender differences in any type of communication might also use: (women OR gender OR girls OR men OR boys)
Not sure what search terms to use? Look for information about your article in the background resources listed on this page, or check for your topic on Google or Wikipedia. These are all good sources for keywords to use.
Too many articles leaving you overwhelmed? Add more search terms. The more words in your search, the fewer results you should see, since they will have to include ALL of those words
