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