• If you are trying to use Boolean operators, they must be ALL CAPS: ho ((chieu sach) OR (hieu lang)) - thanh cung ((tham nhung) OR (thi nhung)) cong dan phan cau.
• The words AND, OR and NOT may confuse the search; try adding quotes: "ho ((chieu sach) or (hieu lang)) - thanh cung ((tham nhung) OR (thi nhung)) cong dan phan cau".
