• Performing a fuzzy search may retrieve terms with similar spellings: ho chieu sang - hanh trung doan phung ((cong manh) OR (cong danh)) ((toan cau) or (toan cao))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: ho chieu sang - hanh trung doan phung ((cong manh) OR (cong danh)) ((toan cau) OR (toan cao))*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "ho chieu sang - hanh trung doan phung ((cong manh) OR (cong danh)) ((toan cau) or (toan cao))*".
