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