• The words AND, OR and NOT may confuse the search; try adding quotes: "ho chieu sang - canh manh cua nhung cong ((((van phan) OR (ban thanh))) OR (luan phan)) cau~".
• Adding a wildcard symbol may retrieve word variants: ho chieu sang - canh manh cua nhung cong ((((van phan) OR (ban thanh))) OR (luan phan)) cau*.
