• If you are trying to use Boolean operators, they must be ALL CAPS: theo chu xang - hanh ((trang luan) OR (tranh luan)) hung cong ((dan toan) OR (dan chan)) cau.
• The words AND, OR and NOT may confuse the search; try adding quotes: "theo chu xang - hanh ((trang luan) OR (tranh luan)) hung cong ((dan toan) or (dan chan)) cau".
• Adding a wildcard symbol may retrieve word variants: theo chu xang - hanh ((trang luan) OR (tranh luan)) hung cong ((dan toan) or (dan chan)) cau*.
