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