trung thanh » truong thanh
thuong cong » thong cong, thuong con, thuong dong
theo chieu » theo tieu, theo chu, thi chieu

• If you are trying to use Boolean operators, they must be ALL CAPS: ((ho chieu) OR (theo chieu)) xanh - thanh trung thanh thuong cong ((manh toan) OR (anh tuan)) cau~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((ho chieu) or (theo chieu)) xanh - thanh trung thanh thuong cong ((manh toan) OR (anh tuan)) cau~".
• Adding a wildcard symbol may retrieve word variants: ((ho chieu) or (theo chieu)) xanh - thanh trung thanh thuong cong ((manh toan) OR (anh tuan)) cau*.
