我想搜索范围从7000到8000的uidNumber。我如何在LDAP3中做到这一点？

from ldap3 import Server, Connection, SUBTREE, ALL

# 连接到LDAP服务器
server = Server('ldap.example.com', port=389)
conn = Connection(server, user='cn=admin,dc=example,dc=com', password='password')
conn.bind()

# 设置搜索条件
base_dn = 'dc=example,dc=com'
filter_str = '(&(objectClass=person)(uidNumber>=7000)(uidNumber<=8000))'

# 执行搜索操作
conn.search(base_dn, filter_str, search_scope=SUBTREE, attributes=ALL)

# 获取搜索结果
for entry in conn.entries:
    print(entry.entry_dn)

# 断开与LDAP服务器的连接
conn.unbind()
