• If you are trying to use Boolean operators, they must be ALL CAPS: te sach 6 tang xa hoi. hieu ve ((((cham luc) OR (cham cuu))) OR (cham soc)) va danh cau su triet.
• Adding a wildcard symbol may retrieve word variants: te sach 6 tang xa hoi. hieu ve ((((cham luc) or (cham cuu))) or (cham soc)) va danh cau su triet*.
