• The words AND, OR and NOT may confuse the search; try adding quotes: "((theo tieu) or (doi chieu)) xanh - anh nang cua hang cong van ((tuan cau) OR (tuan cu))~".
• Adding a wildcard symbol may retrieve word variants: ((theo tieu) or (doi chieu)) xanh - anh nang cua hang cong van ((tuan cau) OR (tuan cu))*.
