Search Types
Users can choose either a Boolean, Concept, or Pattern Search at the top of the search screen.
Boolean Boolean searches will find the exact terms as entered. To narrow the results of a search, terms can be combined with AND, OR, and NOT and placed in parentheses.
- Connecting two terms with AND means both terms must be present.
- Connecting two terms with OR means either term can be present.
- NOT followed by a term means that the term must not appear in the search results.
- Parentheses are used to combine sets of Boolean expressions.
For example, to search for information on HIV/AIDS in correctional facilities, enter:
Concept Concept searches will find not only the search words and phrases but also related concepts. For example, in a concept search for the term "law," the system will also search for related terms, such as "lawyer" and "legal."
Pattern Pattern searches will find both the search terms and terms with similar spellings. This type of search is helpful in retrieving terms or names with alternative spellings or common misspellings. For example, a pattern search for the term "theater" will also search for alternative spellings, such as "theatre."
