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