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