• The words AND, OR and NOT may confuse the search; try adding quotes: "((hoc thien) or (hoc thieu)) tinh - thanh trung cua nhung cong danh ((xuan ban) OR (xuat ban))~".
• Adding a wildcard symbol may retrieve word variants: ((hoc thien) or (hoc thieu)) tinh - thanh trung cua nhung cong danh ((xuan ban) OR (xuat ban))*.
