• The words AND, OR and NOT may confuse the search; try adding quotes: "((ho chinh) OR (hoa chinh)) sach - hanh dung cua truong ((cong tac) or (cong san)) toan tap~".
• Adding a wildcard symbol may retrieve word variants: ((ho chinh) OR (hoa chinh)) sach - hanh dung cua truong ((cong tac) or (cong san)) toan tap*.
