• If you are trying to use Boolean operators, they must be ALL CAPS: o ((chau tinh) OR (ha tinh)) - thanh tra cua khong cong ((san toan) OR (van toan)) cau.
• The words AND, OR and NOT may confuse the search; try adding quotes: "o ((chau tinh) or (ha tinh)) - thanh tra cua khong cong ((san toan) OR (van toan)) cau".
