The terms you enter in the Search Box matter!
They will impact the results you receive and ultimately the resources that will help you to write your research paper.
Keywords are important words and concepts drawn from your research question. One way to quickly identify keywords is to eliminate all words (other than nouns) from your research question. Once you have identified all of the keywords from your research question then you will need to start thinking about amplifying your search terms by using synonyms for your keywords and integrating these terms into your searches.
