• If you are trying to use Boolean operators, they must be ALL CAPS: thuoc sach ((ky nang) OR (v nang)) ma hoa. hieu ve cham xuc ((va danh) OR (va dinh)) vi cuu tre*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "thuoc sach ((ky nang) or (v nang)) ma hoa. hieu ve cham xuc ((va danh) OR (va dinh)) vi cuu tre*".
