• The words AND, OR and NOT may confuse the search; try adding quotes: "hoc chieu xanh - ((hanh tranh) OR (canh tranh)) cua hoang ((luong vat) or (vuong tat)) quan cau~".
• Adding a wildcard symbol may retrieve word variants: hoc chieu xanh - ((hanh tranh) OR (canh tranh)) cua hoang ((luong vat) or (vuong tat)) quan cau*.
