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