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