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