Help > Searching: Boolean Searching
Boolean Searching lets you combine multiple search criteria in various ways, broadening or narrowing search results based on indexed terms and/or keywords you select. To perform a search with more than one term per search field, you place a Boolean operator between each term.
There are four Boolean operators that can be incorporated into a search: AND, OR, NOT, NEAR.
The OR operator:
Placing OR between search terms broadens a search, retrieving all records containing either term.
Example: Arts OR Education will return records that contain only Arts, only Education, or both Arts and Education.
Note: The OR operator is the default operator placed between terms when you select more than one from an index. You can replace OR by highlighting it, pressing Delete or Backspace and typing another operator in its place.
The AND operator:
The AND operator between search terms narrows a search, retrieving only records containing both terms.
Example: Arts AND Education will return records that contain both Arts and Education.
The NOT operator:
The NOT operator limits a search, excluding records with terms you enter to the right of the NOT operator.
Example: Arts NOT Education will return those records that contain Arts as long as they do not also contain Education.
The NEAR operator:
The NEAR operator limits a search to records that include one or more terms in proximity to one another.
Example: Arts <NEAR> Education will return records that contain Arts appearing in proximity to Education.
Note: The NEAR Boolean operator is the only one that must be surrounded by <brackets> in order for the search to work correctly.
