    Following calls would result in at least 3 database queries (or 6 queries 
when getCount=true):
    - getUsersLookup()
    - getGroupsLookup()
    - roleStore.getRoles()
    
    Is it possible to retrieve user/group/role names in a single query, with 
something like the following:
    
    (SELECT user_name AS principal_name, 0 AS principal_type FROM x_user WHERE 
user_name LIKE 'r%' AND is_visible = 1 ORDER BY user_name LIMIT 5)
    UNION
    (SELECT group_name AS principal_name, 1 AS principal_type FROM x_group 
WHERE group_name LIKE 'r%' AND is_visible = 1 ORDER BY group_name LIMIT 5)
    UNION
    (SELECT name AS principal_name, 2 AS principal_type FROM x_role WHERE name 
LIKE 'r%' ORDER BY name LIMIT 5)
    ORDER BY principal_name
    LIMIT 5;
