Construct Search Strategies

Create search by combining concepts with Boolean operators. Use subject terms and keywords in combination.

Boolean Logic Operators:

AND

retrieve items with both concepts/terms

fall AND prevention

OR

retrieve items with either concept/term

fall OR trip OR slip

NOT

excludes concepts from results

fall NOT stand

                                               

- Identify key concepts and related terms of your topic

- Select subject terms using database controlled vocabulary

- Search each concept individually

- Combine multiple search terms using Boolean operators (AND, OR)

- Refine your results by using limits such as publication date, type, population group, age that will reduce search results

- Remember that searching for specific information can be a complex process
