• If you are trying to use Boolean operators, they must be ALL CAPS: thuat sac ky mang may khoa. hieu ((ve cam) OR (vu cham)) xuc ((va dinh) OR (van dinh)) vai 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 (vu cham)) xuc ((va dinh) OR (van dinh)) vai cua tu*".
