• If you are trying to use Boolean operators, they must be ALL CAPS: ho ((chieu sang) OR (trieu tinh)) - thanh trung cua hang cong ((van tan) OR (van tai)) cao*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "ho ((chieu sang) or (trieu tinh)) - thanh trung cua hang cong ((van tan) OR (van tai)) cao*".
