cong thanh » dong thanh, cong trinh, cong tan
cong danh » cuong danh, cong dan, cong khanh

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