Library resources include options to combine keywords using: AND, OR, & NOT. You can type them in as shown in the search examples below. These Boolean operators may also appear by default, with multiple search boxes available for combining terms. You may need to select Advanced Search to access this feature.
- AND: used to limit a search by requiring the presence of two or more terms/phrases in the search results
- OR: used to broaden a search while staying on topic by incorporating synonyms or interchangeable terms/phrases
- NOT: used to exclude an extraneous or irrelevant terms/phrases from the search results
- Use quotation marks to search for a phrase, and prompts the database to return results with the words searched for in the specified sequence.
- Keep phrases brief; typically 2 - 4 words.
These examples are starting points, or simple searches that utilize core research concepts. They would likely result in hundreds or thousands of search results that you could narrow using the limiting options in the database:
- stroke AND diet
- cancer AND malnutrition
- malignancy OR metastasis
- diabetes NOT gestational
- ("heart disease" OR "cardiovascular disease") AND (diet OR food)
