• If you are trying to use Boolean operators, they must be ALL CAPS: thu sach y mang xa hoi. hieu ((va cam) OR (va cham)) xuc ((va thanh) OR (ban thanh)) phan cua tre.
• The words AND, OR and NOT may confuse the search; try adding quotes: "thu sach y mang xa hoi. hieu ((va cam) or (va cham)) xuc ((va thanh) OR (ban thanh)) phan cua tre".
• Adding a wildcard symbol may retrieve word variants: thu sach y mang xa hoi. hieu ((va cam) or (va cham)) xuc ((va thanh) OR (ban thanh)) phan cua tre*.
