Using AND, OR, and NOT
Verity has many powerful operators and modifiers available for searching. However, users might use only the most
basic operators—AND, OR, and the modifier NOT. The following are a few important points:
• You can type operators in uppercase or lowercase letters.
• Verity reads operators from left to right.
• The AND operator takes precedence over the OR operator.
• Use parentheses to clarify the search. Terms enclosed in parentheses are evaluated first; innermost parentheses are
evaluated first when there are nested parentheses.
• To search for a literal AND, OR, or NOT, enclose the literal term in double-quotation marks; for example:
love "and" marriage
Note: Although NOT is a modifier, you use it only with the AND and OR operators. Therefore, it is sometimes casually
referred to as an operator.
