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