• Performing a fuzzy search may retrieve terms with similar spellings: ho chieu sach - hanh tranh luan trang ((nong manh) OR (nong lanh)) ((toan cau) or (toan tap))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: ho chieu sach - hanh tranh luan trang ((nong manh) OR (nong lanh)) ((toan cau) OR (toan tap))*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "ho chieu sach - hanh tranh luan trang ((nong manh) OR (nong lanh)) ((toan cau) or (toan tap))*".
