• If you are trying to use Boolean operators, they must be ALL CAPS: thu sac ky mang ((danh hoa) OR (nganh hoa)). hieu ((va cam) OR (va cham)) duc va dinh viet cua te*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "thu sac ky mang ((danh hoa) OR (nganh hoa)). hieu ((va cam) or (va cham)) duc va dinh viet cua te*".
