• If you are trying to use Boolean operators, they must be ALL CAPS: theo chieu tinh - anh thong quang ((dung phong) OR (rung phong)) van ((tuan cau) OR (toan cau))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "theo chieu tinh - anh thong quang ((dung phong) OR (rung phong)) van ((tuan cau) or (toan cau))~".
• Adding a wildcard symbol may retrieve word variants: theo chieu tinh - anh thong quang ((dung phong) OR (rung phong)) van ((tuan cau) or (toan cau))*.
