hoi hieu » hoi phieu, hoi tieu, moi hieu
lan hung » van hung, luan chung, lan phuong

• If you are trying to use Boolean operators, they must be ALL CAPS: ((ho hieu) OR (hoi hieu)) lang - thanh trung lan hung huong ((dan toan) OR (dan than)) cau~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((ho hieu) OR (hoi hieu)) lang - thanh trung lan hung huong ((dan toan) or (dan than)) cau~".
• Adding a wildcard symbol may retrieve word variants: ((ho hieu) OR (hoi hieu)) lang - thanh trung lan hung huong ((dan toan) or (dan than)) cau*.
