• The words AND, OR and NOT may confuse the search; try adding quotes: "ho chieu sach - thanh trung cua nhung cong ((tap doan) or (((van tan) OR (van tuan)))) tap~".
• Adding a wildcard symbol may retrieve word variants: ho chieu sach - thanh trung cua nhung cong ((tap doan) or (((van tan) OR (van tuan)))) tap*.
