hanh trung » thanh trung, hanh trang, manh trung

mot chieu » doi chieu, ho chieu

• If you are trying to use Boolean operators, they must be ALL CAPS: ((theo chieu) OR (mot chieu)) sach - hanh trung cua phuong song ((van tuan) OR (van ban)) tai~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((theo chieu) or (mot chieu)) sach - hanh trung cua phuong song ((van tuan) OR (van ban)) tai~".
• Adding a wildcard symbol may retrieve word variants: ((theo chieu) or (mot chieu)) sach - hanh trung cua phuong song ((van tuan) OR (van ban)) tai*.
