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