4.1 Search Tips: Using "and" and "or"

Put simply, use AND between your terms if you want fewer results with both criteria. For example, "computers AND elementary" will give you only results that contain both words.

Every time you add a limit (e.g. year, language, document type) the system uses AND to combine it with your search terms. You can also use more than one search term and combine your search boxes with AND.

Use OR if you are not getting enough results, and you need to broaden your search with synonyms or related terms. For example, "deaf" OR "hearing impaired" would be a good search if you did not get enough results using the term "deaf". Adjust the box to the left of the search box if OR is what you need.
