Ldap user filter not working correctly

Hi,
I have a nextcloud 29.
I want to see only 2 groups. in users

my config is below.
advanced settings :

baseuser tree
DC=subdomain,DC=domain
DC=subdomain,DC=domain

basegrup tree is same:
DC=subdomain,DC=domain
DC=subdomain,DC=domain

Group Search Attributes: ou=NEXTCLOUD,DC=subdomain,DC=domain

when ı use this query in Users tab ı find 800+ users…
(&(|(objectclass=person)))

But ı want to see only 10 members in 2 groups…
when ı write this query ı cant find any person…
why and how to solve this problem thanks…

(&(|(objectclass=person)))(memberOf=cn=GRUP1,ou=NEXTCLOUD,dc=subdomain,dc=domain)
