• If you are trying to use Boolean operators, they must be ALL CAPS: hoi hieu lang - hanh trang cua tong cong ((thanh toan) OR (((van tan) OR (van tuan)))) cao~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "hoi hieu lang - hanh trang cua tong cong ((thanh toan) or (((van tan) OR (van tuan)))) cao~".
• Adding a wildcard symbol may retrieve word variants: hoi hieu lang - hanh trang cua tong cong ((thanh toan) or (((van tan) OR (van tuan)))) cao*.
