• If you are trying to use Boolean operators, they must be ALL CAPS: su sach ky danh xa hoi. hieu qua cai xuc ((((va hanh) OR (ban hanh))) OR (ban thanh)) vi cuu tre.
• Adding a wildcard symbol may retrieve word variants: su sach ky danh xa hoi. hieu qua cai xuc ((((va hanh) or (ban hanh))) or (ban thanh)) vi cuu tre*.
