• The words AND, OR and NOT may confuse the search; try adding quotes: "ho ((chieu xanh) or (chieu sang)) - canh tranh cua chong cong van ((tuan tap) OR (toan tap))~".
• Adding a wildcard symbol may retrieve word variants: ho ((chieu xanh) or (chieu sang)) - canh tranh cua chong cong van ((tuan tap) OR (toan tap))*.
