Evidence operators can specify either a basic word search or an intelligent word search. A basic word search finds documents that contain only the word or words specified in the query. An intelligent word search expands the query terms to create an expanded word list so that the search returns documents that contain variations of the query terms. For example, the

modifier. (For examples and more detailed information, see "MANY" in Chapter 4.)
