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