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