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