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