Search Tips for Philosophy

How do I choose keywords for my searches?

  • Words to include
    You would want to include, the main ideas of your research question, for instance you could use a philosopher's name and their work and/or philosophical idea or theory.
  • Use quotation marks
    If the name is longer than one word, you can optimize your search by putting quotation marks around the title. Using quotation marks will ensure that the database finds results that use that exact phrase.  
  • Use AND
    To search for multiple concepts at the same time, you need to link your search terms with AND. This strategy will narrow your search. 
Nietzsche AND "Thus Spoke Zarathustra"

Found too many results?

  • Add more keywords
    If you find that you are retrieving too many results, try adding more keywords to further narrow your topic.
Nietzsche AND "Thus Spoke Zarathustra" AND existentialism

Found too few results?

  • Use OR
    At times you may not find much information on the subject have chosen. In this case you can try broadening your search by using OR to link your terms. This strategy will broaden your search because it will return results that mention either Nietzsche OR existentialism
