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