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