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