How to Limit Your Medline and CINAHL Searches

Search Tips

Use the Boolean Operators (AND, OR, NOT) to improve your search results:

  • use AND to combine search terms: elementary AND "special education" to get results on elementary special education.
  • use OR to combine search terms:  elementary OR "special education" to get results on either elementary or special education.
  • use NOT to combine search terms:  elementary NOT "special education" to get results about elementary that excludes special education

Use truncation to improve your search results:

  • use quotation marks (") to indicate a phrase:  results on "special education" rather than special and education
  • use an asterisk (*) as a wild card: education* will give wider results, education, educational, educations, etc
  • use a question mark (?) to replace a single character:  wom?n will give you both woman and women.

You can also limit your search results to only materials owned by Rockhurst or search for materials from all the other libraries in the Kansas City Cluster.

Use these worksheets to help develop your topic, create keywords and work through catalog or databases searches.
