Social Justice: Databases

Databases

Search like a pro

Choose your words 

  • Keywords are descriptive words or important concepts. Search using just keywords rather than full sentences.

  • Omit words like "the", "a", "are", "it" from the search. Most databases do not search for these words and they can impact the search results.

  • Identify keywords from your background research.

  • Brainstorm synonyms for keywords and search all possible concepts.

  • Look up your keywords in the database Subject Headings or Thesaurus section to determine if you are using the correct phrase or spelling. 

  • Put quotation marks around phrases to retrieve results with the exact phrase ("mouse and rat")

  • The asterisk (*) wildcard, also known as the truncation wildcard, is generally used to find word endings. (Metaboli* will find results with metabolism, metabolic, metabolite, metabolites, metabolizing, and metabolically)

Improve Search Results by Connecting Keywords with Boolean Logic

Boolean (pronounced BOO-lee-an) are connectors between search terms. They can be used to make sophisticated searches. They are used to combine different concepts, combine similar concepts or eliminate concepts. Boolean uses three simple terms, AND, OR, NOT. 

  • Use AND to retrieve results with both concepts (mouse AND rat)

  • Use OR to retrieve either keyword (mouse OR rat)

  • Use NOT to omit a keyword (mouse NOT rat)

The areas shaded in black represent the database search results when using a specific Boolean Operator between two keywords.

When using this image as a teaching material, it is recommended to assign example keywords to A and B to provide concrete examples of how database search results change when using Boolean Operators.

Focus Results with Limiters

  • Full Text will limit results to articles with full text. 

  • Peer Reviewed limits results to articles from peer-reviewed journals. 

  • Scholarly Journals limits results to articles from academic publishers of both "peer-reviewed" and not "peer-reviewed" journals intended for an academic audience. 

  • Date Published can be used to limit results to a specified date range.
