• If you are trying to use Boolean operators, they must be ALL CAPS: ho nhieu tang - thanh trung luan phong thong ((dan than) OR (((ban than) OR (ban thanh)))) cau~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "ho nhieu tang - thanh trung luan phong thong ((dan than) or (((ban than) OR (ban thanh)))) cau~".
• Adding a wildcard symbol may retrieve word variants: ho nhieu tang - thanh trung luan phong thong ((dan than) or (((ban than) OR (ban thanh)))) cau*.
