• If you are trying to use Boolean operators, they must be ALL CAPS: ((theo lieu) OR (theo tieu)) tinh - thanh tuong cua thong cong ((san toan) OR (van toan)) cau~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((theo lieu) or (theo tieu)) tinh - thanh tuong cua thong cong ((san toan) OR (van toan)) cau~".
• Adding a wildcard symbol may retrieve word variants: ((theo lieu) or (theo tieu)) tinh - thanh tuong cua thong cong ((san toan) OR (van toan)) cau*.
