• If you are trying to use Boolean operators, they must be ALL CAPS: hoc ((chieu sang) OR (hieu lang)) - thanh luong quan duong ((song van) OR (trong van)) tuan cau.
• The words AND, OR and NOT may confuse the search; try adding quotes: "hoc ((chieu sang) or (hieu lang)) - thanh luong quan duong ((song van) OR (trong van)) tuan cau".
• Adding a wildcard symbol may retrieve word variants: hoc ((chieu sang) or (hieu lang)) - thanh luong quan duong ((song van) OR (trong van)) tuan cau*.
