Multiple search filter components can be combined using Boolean operators expressed in prefix
notation as follows:
(Boolean-operator(filter)(filter)(filter)...)
Boolean-operator is any one of the Boolean operators listed in Table B.2, “Search Filter
Boolean Operators”.
Boolean operators can be combined and nested together to form complex expressions, such
as:
(Boolean-operator(filter)((Boolean-operator(filter)(filter)))
The Boolean operators available for use with search filters include the following:
Operator Symbol Description
AND & All specified filters must be
true for the statement to be
true. For example,
(&(filter)(filter)(filter)...).
OR | At least one specified filter
must be true for the statement

(|(filter)(filter)(filter)...)
NOT ! The specified statement must
not be true for the statement
to be true. Only one filter is
affected by the NOT operator.
For example, (!(filter)).
