Choose keywords that represent the main concepts of your research topic.

• Use AND
  This strategy will narrow your search. 
• Use OR
  This strategy will broaden your search. Put words linked by OR inside parentheses.
• Use quotation marks
  Using quotation marks will ensure that the database finds results that use that exact phrase.  
• Use * 
  The * symbol tells the database to search for alternative word endings, for example: migrat* will search for migrate, migrating, migration​
