• If you are trying to use Boolean operators, they must be ALL CAPS: su sach ky dang xa hoi. hieu ((((van cam) OR (van dam))) OR (van nam)) loc va thanh vi cuu tre.
• Adding a wildcard symbol may retrieve word variants: su sach ky dang xa hoi. hieu ((((van cam) or (van dam))) or (van nam)) loc va thanh vi cuu tre*.
