more as one attributes in filter

[<Bet...@gm...>]

Hello, i have an new question over Net::LDAP ... i hope is my last Question
for this Project.
How can i search for more as One Attribute, and how can i attach the
Attributes (and, or)
in RFC1960 and other RFCs stand this form:
(cn=Frank) (| (cn=thomas))
but when i'm write this in my code, i dont get Entries from the x.500 Server
but the Code is 87.
espacially i want Attach (link) the Modifikation Timestamp Attribut so that
i can say, i want all Entries, that are modifikatet between Time1 and Time2
Pseudocode, which dosn't work
filter=> "(modifyTimestamp >= 20020101000000Z) AND (modifyTimestamp >=
20020131235959Z)"

how can i do this?
Thanks for the Answers, ands also for the Answers from Yesterday.
Frank
