Boolean operators combine and exclude terms in a particular way. The three main operators are 'and', 'or', and 'not'. The ' and ' operator is useful if you need to narrow a search. The ' or ' operator widens a search so must be used with care. The ' not ' operator can be useful for narrowing a search, but must be used with caution because some useful records may include a passing reference to a term you exclude.
Parentheses Use parentheses to define the logical order in which a multiple-term query is performed.
Proximity operators Use proximity operators to narrow a search, but with greater precision than the and operator. In order to be retrieved, not only must the documents contain both terms, but the terms must occur within a certain distance of each other. Wild Cards Wild cards are used in place of one or more characters in a word when you are designing a search on the Search screen. If you want to clear all of the entries that you have made on the Search screen, click the Clear button near the bottom of the window. If your search finds more than one record, you will be shown a list of profiles of documents on the Search Results screen.
