Use:

• Always capitalize Boolean Operators (AND, OR, NOT) in your search statement.

• AND
  This strategy will narrow your search. 
• OR
  This strategy will broaden your search. Put words linked by OR inside parentheses ( ).
• Quotation marks " "
  Using quotation marks will ensure that the database finds results that use that exact phrase.
• Asterisk * 
  The * symbol tells the database to search for alternative word endings, for example: cultur* will search for culture, cultures, cultural

How do I choose keywords for my searches?

• Words to include
  When you choose keywords for your search, you would want to include just the main ideas of your research question
• Use quotation marks around phrases, not single terms
  If the topic is longer than one word, you can optimize your search by putting quotation marks around it. Using quotation marks will ensure that the database finds results that use that exact phrase.  
• Use AND
  To search for two topics together, you need to link your search terms with AND. This strategy will narrow your search. 

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.

Found too few results?

• Use OR
  If you are searching for a really specific topic, you might not find enough information. In this case, you can try broadening your search by using fewer keywords, or by using OR to add synonyms for your current search terms. If you link synonyms with or, make sure to put them inside parentheses.
