• If you are trying to use Boolean operators, they must be ALL CAPS: ho ((chieu xanh) OR (chieu sach)) - canh tranh cua hang dong ((ban thanh) OR (ban hang)) bac~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "ho ((chieu xanh) OR (chieu sach)) - canh tranh cua hang dong ((ban thanh) or (ban hang)) bac~".
• Adding a wildcard symbol may retrieve word variants: ho ((chieu xanh) OR (chieu sach)) - canh tranh cua hang dong ((ban thanh) or (ban hang)) bac*.
