• If you are trying to use Boolean operators, they must be ALL CAPS: ho chieu tinh - thanh trung ((dao thong) OR (dao khong)) cong ((dan toan) OR (van toan)) cao.
• The words AND, OR and NOT may confuse the search; try adding quotes: "ho chieu tinh - thanh trung ((dao thong) OR (dao khong)) cong ((dan toan) or (van toan)) cao".
• Adding a wildcard symbol may retrieve word variants: ho chieu tinh - thanh trung ((dao thong) OR (dao khong)) cong ((dan toan) or (van toan)) cao*.
