• If you are trying to use Boolean operators, they must be ALL CAPS: ((thi kieu) OR (thi kim)) tinh - ((hanh tranh) OR (hanh trang)) cua duong cong dan toan cao.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((thi kieu) OR (thi kim)) tinh - ((hanh tranh) or (hanh trang)) cua duong cong dan toan cao".
• Adding a wildcard symbol may retrieve word variants: ((thi kieu) OR (thi kim)) tinh - ((hanh tranh) or (hanh trang)) cua duong cong dan toan cao*.
