• If you are trying to use Boolean operators, they must be ALL CAPS: ((mot chieu) OR (hoc hien)) xanh - thanh trung cua ((nhung cong) OR (thong cong)) dan than cap.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((mot chieu) or (hoc hien)) xanh - thanh trung cua ((nhung cong) OR (thong cong)) dan than cap".
• Adding a wildcard symbol may retrieve word variants: ((mot chieu) or (hoc hien)) xanh - thanh trung cua ((nhung cong) OR (thong cong)) dan than cap*.
