• If you are trying to use Boolean operators, they must be ALL CAPS: thu sach ky lang mai khoa. hieu ve cham xuc ((va hang) OR (va lang)) va ((cuu tre) OR (cau tren))*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "thu sach ky lang mai khoa. hieu ve cham xuc ((va hang) OR (va lang)) va ((cuu tre) or (cau tren))*".
