• Performing a fuzzy search may retrieve terms with similar spellings: nuoc sach y mang may khoa. hieu ((ve cham) or (tu cham)) xuc van dinh vi ((cua te) OR (cua tu))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: nuoc sach y mang may khoa. hieu ((ve cham) OR (tu cham)) xuc van dinh vi ((cua te) OR (cua tu))*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "nuoc sach y mang may khoa. hieu ((ve cham) or (tu cham)) xuc van dinh vi ((cua te) OR (cua tu))*".
