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