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