OneSearch offers the following Boolean operations: AND, OR, NOT, +, -
The use of these ALL CAPS characters can be used to make queries more specific. By default, all terms in a search are combined with the AND operator.
To expand the results set, use the OR operator: marijuana OR cannabis will return items that contain either term.
This can be combined with phrases such as “side effects” OR “health effects.”
To do this search by hand, enter this phrase into the search box:
marijuana OR cannabis AND ("side effects" OR "health effects")
This will search for both marijuana OR cannabis related to "side effects" or "health effects."
Use the “+” character directly before a term to indicate that it must be included in the results. When searching for “snow +cold OR avalanche” the word “cold” will be included in all results.
To exclude items in OneSearch, use the NOT operator or “-” character before a term. When used in the following query “animal NOT dog” the results will not include the term “dog.”
