• If you are trying to use Boolean operators, they must be ALL CAPS: theo chu sach - manh huong cua thong cong san ((((tran cao) OR (trang cho))) OR (toan ban))~.
• Adding a wildcard symbol may retrieve word variants: theo chu sach - manh huong cua thong cong san ((((tran cao) or (trang cho))) or (toan ban))*.
