• Performing a fuzzy search may retrieve terms with similar spellings: te sac ky hang hoa hoi. hieu he ((nam thuc) OR (nam thu)) va hang hai ((cua viet) or (cua vat))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: te sac ky hang hoa hoi. hieu he ((nam thuc) OR (nam thu)) va hang hai ((cua viet) OR (cua vat))*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "te sac ky hang hoa hoi. hieu he ((nam thuc) OR (nam thu)) va hang hai ((cua viet) or (cua vat))*".
