• If you are trying to use Boolean operators, they must be ALL CAPS: ho ((chinh sach) OR (chieu sang)) - thanh ((trung cap) OR (truong cao)) nhung cong dan than cap.
• The words AND, OR and NOT may confuse the search; try adding quotes: "ho ((chinh sach) or (chieu sang)) - thanh ((trung cap) OR (truong cao)) nhung cong dan than cap".
• Adding a wildcard symbol may retrieve word variants: ho ((chinh sach) or (chieu sang)) - thanh ((trung cap) OR (truong cao)) nhung cong dan than cap*.
