You may use AND, OR or NOT in your search string.
AND is assumed between words when no operator is included.
Use AND when you want all terms to appear in the records.
Example:
wau=shakespeare AND wti=midsummer
retrieves records having shakespeare as an author keyword and midsummer as a title keyword.
Use OR when you are searching for synonyms.
Example:
wrd=heart OR cardiac
retrieves all records having heart or cardiac anywhere in the record.
Use NOT when you want the first term to be included in the records but not the second term.
Example:
wsu=education NOT wsu=higher
retrieves records that have education as a subject keyword, but not higher as a subject keyword.
Use ( ) parentheses to create complex searches.
Statements enclosed in parentheses are performed first by the system. If there are no parentheses, the AND operator is processed first, OR is next and NOT is processed last.
Example:
wrd=(drug or substance) and (abuse or addiction)
the words linked by OR will be processed first because they are within the parentheses. The results of the OR set will then be combined with the AND.
To search for a phrase, use quote marks.
Example:
wsu= "civil war"
retrieves records that have the phrase "civil war" in subject keywords.
Normal truncation characters may be used in command language searches
