Then to create a search string, select specific keywords and combine them using Boolean connectors (or operators).
When searching, Boolean connectors allow you to "tell" a Library resource what each result must or must not include.
Boolean | Example | Description |
"Quotation marks" | "food insecurity" | Each result will contain the exact phrase included in the quotes |
AND Google Scholar: A space = AND |
"food insecurity" AND income Google Scholar: "food insecurity" income |
Each result will contain all keywords |
OR + parentheses () | ("food insecurity" OR "food security") | Each result will contain at least one of the keywords connected by OR and included in the parentheses |
NOT | ("food insecurity" OR "food security") NOT "southern idaho" | Only results that do not include the specified keyword will appear in the results list |
Asterisk (*) | econom* = economy, economics, economical, etc. | Each result will include variations of the root of the keyword |
Combine AND, quotation marks, OR and parentheses, and asterisks * to create a more complex searches.
Example: ("food insecurity" OR "food security") AND econom* AND Idaho
