• The words AND, OR and NOT may confuse the search; try adding quotes: "ho ((chieu sach) or (nhieu tang)) - canh tranh cua ban phuong doan ((phan cau) OR (phan tu))~".
• Adding a wildcard symbol may retrieve word variants: ho ((chieu sach) or (nhieu tang)) - canh tranh cua ban phuong doan ((phan cau) OR (phan tu))*.
