• Performing a fuzzy search may retrieve terms with similar spellings: te sach ky ((nang xa) or (nang ma)) hoi. hieu va chat soc va danh di ((cua viet) OR (cua vat))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: te sach ky ((nang xa) OR (nang ma)) hoi. hieu va chat soc va danh di ((cua viet) OR (cua vat)).
• The words AND, OR and NOT may confuse the search; try adding quotes: "te sach ky ((nang xa) or (nang ma)) hoi. hieu va chat soc va danh di ((cua viet) OR (cua vat))".
• Adding a wildcard symbol may retrieve word variants: te sach ky ((nang xa) or (nang ma)) hoi. hieu va chat soc va danh di ((cua viet) OR (cua vat))*.
