• Performing a fuzzy search may retrieve terms with similar spellings: tu sai ky ((sang ma) or (tang ma)) hoi. hieu ve cam thuc van anh bai ((ca treo) OR (cau treo))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: tu sai ky ((sang ma) OR (tang ma)) hoi. hieu ve cam thuc van anh bai ((ca treo) OR (cau treo))*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "tu sai ky ((sang ma) or (tang ma)) hoi. hieu ve cam thuc van anh bai ((ca treo) OR (cau treo))*".
