Online Library Orientation: 2a. Use Your Keywords to Build Search Statements

An online introduction to the library's resources for BSC students.

Putting Your Keywords Together Into A Search Statement

Once you have identified your keywords (and brainstormed additional synonyms and related concepts) it's time to put the keywords together into a search statement!


Important database search tips: 

  • Use quotation marks around exact phrases 
    • This tells the database you only want results where the words are together in that exact order, with that exact spelling
      • Example: enter cardiovascular disease as "cardiovascular disease"


  • To search multiple keywords or phrases together, join them together with AND
    • ‚ÄčThis will return results with all the words entered
      • Example:  "animal testing" AND "United States"


  • To search multiple synonyms of one concept at once, put OR between the keywords 
    • This tells the database that you will accept either word
      • Example: "fast fashion" OR sweatshops
      • This will get you results with either the phrase "fast fashion" or the word "sweatshops"


  • Use parentheses to group terms when your search statement includes more than one type of search operator (AND, OR)
    • This tells the database how to interpret your search statement
      • Example:  (elderly OR "older adults" OR geriatric) AND (loneliness OR "social isolation")
      • This will get you results that have any of the three words for elderly AND either of the terms for loneliness 


  • If you are still struggling to find results, make sure that you are using the language that experts use!
    • Do some background searching on Google and Wikipedia to make sure you are using the correct terminology for your keywords
    •  Scan any relevant articles you find for other keywords that you can use
