• If you are trying to use Boolean operators, they must be ALL CAPS: ho ((chieu sach) OR (trieu tinh)) - ((hanh mang) OR (nhanh mang)) cua dung cong van toan tap.
• The words AND, OR and NOT may confuse the search; try adding quotes: "ho ((chieu sach) or (trieu tinh)) - ((hanh mang) OR (nhanh mang)) cua dung cong van toan tap".
• Adding a wildcard symbol may retrieve word variants: ho ((chieu sach) or (trieu tinh)) - ((hanh mang) OR (nhanh mang)) cua dung cong van toan tap*.
