Using Compound Search Filters

Multiple search filter components can be combined using Boolean operators expressed in prefix notation as follows:

(Boolean-operator(filter)(filter)(filter)...)

where Boolean-operator is any one of the Boolean operators listed in Table 13–6.

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:

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 to be true. For example, 

(|(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))

The use of the NOT operator results in an unindexed search. 

Boolean expressions are evaluated in the following order:
