Whats a Boolean search?
Boolean Searching lets you combine multiple search criteria in various ways, broadening or narrowing search results based on index entries and/or keywords you select. Boolean searching is a powerful tool, providing great flexibility in designing complex search strategies. However, this flexibility can also be confusing. Experimentation is the best way to ensure you get accurate results. To perform a search with more than one term per search field, you place a Boolean operator between each term. There are three Boolean operators that can be incorporated into a search. They are the words: AND, OR and NOT.
