• If you are trying to use Boolean operators, they must be ALL CAPS: ((25 trieu) OR (30 trieu)) tinh - thanh tra quan dung cong ha ((toan cau) OR (toan cao)).
• The words AND, OR and NOT may confuse the search; try adding quotes: "((25 trieu) or (30 trieu)) tinh - thanh tra quan dung cong ha ((toan cau) OR (toan cao))".
• Adding a wildcard symbol may retrieve word variants: ((25 trieu) or (30 trieu)) tinh - thanh tra quan dung cong ha ((toan cau) OR (toan cao))*.
