• Performing a fuzzy search may retrieve terms with similar spellings: te sach tham bang van hoi. hieu ((va cam) or (va cao)) thuc vat thanh hai ((cua te) OR (cua tu))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: te sach tham bang van hoi. hieu ((va cam) OR (va cao)) thuc vat thanh hai ((cua te) OR (cua tu))*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "te sach tham bang van hoi. hieu ((va cam) or (va cao)) thuc vat thanh hai ((cua te) OR (cua tu))*".
