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 B-2.
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
>=
<=
=*
~=
Description
Returns entries containing attributes that are greater than
or equal to the specified value. For example,
buildingname >= alpha
Returns entries containing attributes that are less than or
equal to the specified value. For example,
buildingname <= alpha
Returns entries containing one or more values for the
specified attribute. For example,
cn=*
telephonenumber=*
manager=*
Returns entries containing the specified attribute with a
value that is approximately equal to the value specified
in the search filter. For example,
cn~=suret
l~=san fransico
