• If you are trying to use Boolean operators, they must be ALL CAPS: ho ((chieu sach) OR (chiet tach)) - thanh trung cua dung cong ((ban hang) OR (van tuan)) cau*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "ho ((chieu sach) OR (chiet tach)) - thanh trung cua dung cong ((ban hang) or (van tuan)) cau*".
