• Performing a fuzzy search may retrieve terms with similar spellings: te sai ky sang ((ma hoi) OR (ma hoa)). hieu van cam duc ((hoa doanh) or (va dan)) dan cua te~.
• If you are trying to use Boolean operators, they must be ALL CAPS: te sai ky sang ((ma hoi) OR (ma hoa)). hieu van cam duc ((hoa doanh) OR (va dan)) dan cua te*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "te sai ky sang ((ma hoi) OR (ma hoa)). hieu van cam duc ((hoa doanh) or (va dan)) dan cua te*".
