Tips for Creating Advanced Keyword Searches

These tips can be used, in general, with the Library's OneSearch, databases, and on the open Web.

Try Boolean operators or connectors
  • AND = Fewer results. All of your search terms must be found in the results. EXAMPLE: health AND perceptions AND teenagers. You could also just type: health perceptions teenagers.

  • OR = More results. Any one or more of your search terms must be found in a result. EXAMPLE: teens OR teenagers OR adolescents.

  • NOT = Fewer results. Word(s) must be excluded from the results. EXAMPLE: corn NOT toes. The word "toes" would be excluded.

Try a phrase search
  • Find words that appear in a particular order. Type the words in order between quotation marks. EXAMPLE 1: "atkins diet"  EXAMPLE 2: "body mass index"

Try a truncation search
  • Finds words that start with certain letters. Type a word stem, then add an asterisk symbol. EXAMPLE: Nutrit* will find nutrition, nutritionalnutritionally, nutritionist.
Try a nested search
  • Use parentheses to separate search statements so they can be combined and performed in order. Statements inside parentheses are searched first, and the order of operations is left to right. EXAMPLE: (problems OR complications) AND food fads.
Try an index or field search
  • Find words in a particular index or field. EXAMPLE: You can search for words within the Title, Abstract, or Subject field.
