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