• If you are trying to use Boolean operators, they must be ALL CAPS: thuat sac ky mang may hoa. hieu ((ve cam) OR (ve cham)) ((xuc va) OR (tuc va)) dinh vi cua tu*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "thuat sac ky mang may hoa. hieu ((ve cam) or (ve cham)) ((xuc va) OR (tuc va)) dinh vi cua tu*".
