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