• The words AND, OR and NOT may confuse the search; try adding quotes: "theo ((chieu xanh) OR (chieu sang)) - canh tranh cua nhung cong tan ((than cau) or (than cap))~".
• Adding a wildcard symbol may retrieve word variants: theo ((chieu xanh) OR (chieu sang)) - canh tranh cua nhung cong tan ((than cau) or (than cap))*.
