• If you are trying to use Boolean operators, they must be ALL CAPS: vu sach cap tang xa hoi. hieu ((van cam) OR (van lam)) tuc ((va thanh) OR (ban thanh)) vi cuu tre.
• The words AND, OR and NOT may confuse the search; try adding quotes: "vu sach cap tang xa hoi. hieu ((van cam) or (van lam)) tuc ((va thanh) OR (ban thanh)) vi cuu tre".
• Adding a wildcard symbol may retrieve word variants: vu sach cap tang xa hoi. hieu ((van cam) or (van lam)) tuc ((va thanh) OR (ban thanh)) vi cuu tre*.
