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