Using the Boolean operators and a prefix notation, the basic
filters can be combined to form more complex ones. The ‘&’
character represents AND, the ‘|’ character represents OR and the
‘!’ character represents NOT. Here are some examples that
explain how to do that:
Note:
Less or
equal than
(<attr><=<va
lue>)
(sn<=Smith)
Surnames
lexicographically
less than or
equal to Smith.
Presence (<attr>=*) (sn=*)
All surnames.
Filter Type Format Example Matches
AND (&(<filter1>
)(<filter2>)
...)
(&(sn=smith)
(objectclass
=person))
Entries with an
object class of
person and a
surname exactly
equal to Smith.
OR (|(<filter1>
)(<filter2>)
...)
(|(sn=smith)
(cn=*smith))
Entries with a
surname exactly
equal to Smith
or a
commonname
ending in
“smith”.
NOT (!(<filter>)
)
(!(mail=*))
Entries without
a mail attribute.
It is wise to create filters that sort out unwanted entries based on their
object class. For example, in an address book, you might only want to
retrieve entries of the “people” class, with the common name “John”,
leaving out computers called John. This could be achieved with the
following filter: (&(objectclass=person)(cn=john))
