Searching for sources can sometimes lead to frustration if you are overwhelmed with either too many, or, not enough results when searching in databases. This is when using Boolean operators can be helpful!
Use Boolean operators AND, OR, and NOT to narrow or broaden your search results.
- Use AND to:
- Narrow your results
- Inform the database that all search terms must be present in search results
- EX: rivers AND conservation
- Now your search results will be narrowed to only include items which discuss both rivers and conservation!
- Use OR to:
- Broaden your results by connecting two or more search terms
- Inform the database that any of your search terms can be present in search results
- EX: rivers OR conservation
- Now your search results will be broadened to include any items which discuss rivers or conservation!
- Use NOT to:
- Narrow your results by excluding specific search terms
- Inform the database to omit items from your search results which discuss specific search terms
- EX: rivers NOT conservation
- Now your search results will be narrowed to exclude any items which discuss conservation in association with rivers!
