• If you are trying to use Boolean operators, they must be ALL CAPS: ho ((trieu tinh) OR (va tinh)) - thanh trung cua ((thong cong) OR (tong cong)) dan chan cap.
• The words AND, OR and NOT may confuse the search; try adding quotes: "ho ((trieu tinh) or (va tinh)) - thanh trung cua ((thong cong) OR (tong cong)) dan chan cap".
• Adding a wildcard symbol may retrieve word variants: ho ((trieu tinh) or (va tinh)) - thanh trung cua ((thong cong) OR (tong cong)) dan chan cap*.
