Combining keywords with AND & OR

You can use the search commands AND and OR in library databases like PsycInfo to refine your results. When you capitalize these words in your search the database recognizes these as words that tell it to perform a certain action rather than words to find in the articles contained within the database.

  • AND narrows: used between keywords tells the database to limit your search to results that mention all of your keywords. AND is best applied between search bars to join unrelated keywords and will narrow your search. 
  • OR expands: used between keywords tells the database to find results that mention any of your keywords. OR is particularly useful when searching for synonyms and related terms and will broaden your search. 

Examples:

children OR adolescents Finds results that mention either the word children or the word adolescents. Results may include only one of the search terms or both. 
children AND fatigue Find results that mention both the word children and the word fatigue.

Excluding results using NOT

Another search command you can use between keywords is NOT. 

NOT excludes. Using NOT tells the database to find 1 word but not another.

 Example: 

Health NOT nursing Finds articles that include the word health but excludes any article that contains the word nursing.

Use NOT carefully as you can easily exclude relevant results.
