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