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