• Performing a fuzzy search may retrieve terms with similar spellings: te sac ky nang ((me hoi) or (ma hoa)). lieu va cao duc ban hang dai ((cua tre) OR (cua te))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: te sac ky nang ((me hoi) OR (ma hoa)). lieu va cao duc ban hang dai ((cua tre) OR (cua te))*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "te sac ky nang ((me hoi) or (ma hoa)). lieu va cao duc ban hang dai ((cua tre) OR (cua te))*".
