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