• If you are trying to use Boolean operators, they must be ALL CAPS: theo chu xanh - hanh dung cua nhung cong ((dan toan) OR (((van toan) OR (van tuan)))) cau~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "theo chu xanh - hanh dung cua nhung cong ((dan toan) or (((van toan) OR (van tuan)))) cau~".
• Adding a wildcard symbol may retrieve word variants: theo chu xanh - hanh dung cua nhung cong ((dan toan) or (((van toan) OR (van tuan)))) cau*.
