Boolean operators allow terms to be combined. “AND”, “+”, “OR”, “NOT” and “-” are supported.
The OR operator is the default operator. This means that if there is no Boolean operator between two terms, the OR operator is used. The OR operator links two terms and finds a matching document if either of the terms exist in a document.
To search for documents that contain either “learning object” or just “federation” use the query:
"learning object" federation |
"learning object" OR federation |
