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