• If you are trying to use Boolean operators, they must be ALL CAPS: theo chieu sach - ((((lanh tranh) OR (hanh trinh))) OR (hoang manh)) cua thong thuong san van ban~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "theo chieu sach - ((((lanh tranh) OR (hanh trinh))) or (hoang manh)) cua thong thuong san van ban~".
• Adding a wildcard symbol may retrieve word variants: theo chieu sach - ((((lanh tranh) OR (hanh trinh))) or (hoang manh)) cua thong thuong san van ban*.
