Search Tips: Using Boolean Logic
You can use Boolean logic when you are searching a database for journal articles. Boolean "operators" (AND, OR and NOT) define the relationships between the terms you enter in the search bar(s).
- AND can be used between terms to expand the search to include all terms (ex. search for the terms "travel" and "Europe")
- OR allows for results that contain at least one of the terms you enter (ex. "college" OR "university")
- NOT excludes terms so that you can specificy that search results not contain certain terms (USE WITH CAUTION)
The following table illustrates the operation of Boolean terms:
| And | Or | Not |
| Each result contains all search terms. | Each result contains at least one search term. | Results do not contain the specified terms. |
| The search heart and lung finds items that contain both heart and lung. | The search heart or lung finds items that contain either heart or items that contain lung. | The search heart not lung finds items that contain heart but do not contain lung. |
Other Tips:
-
Keyword Searching---search key words in the title, author, and/or subject field (use the drop down menu to change fields. Keyword is usually the default)
- Use quotation marks to search for terms together (useful when searching a certain phrase or the title of an article) ex. "social networking"
- Use an asterisk (*) to search for alternate word endings (ex. immigra* retrieves immigration, immigrant, immigrants, immigrated, etc...)
