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