• If you are trying to use Boolean operators, they must be ALL CAPS: su sach ky trang xa hoi. hieu ve ((cac ly) OR (cac ky)) va han tai ((cuu tre) OR (su tien)).
• Adding a wildcard symbol may retrieve word variants: su sach ky trang xa hoi. hieu ve ((cac ly) or (cac ky)) va han tai ((cuu tre) or (su tien))*.
