• If you are trying to use Boolean operators, they must be ALL CAPS: so sach ky nang xa hoi. hieu ((va cam) OR (va cac)) tuc xa huong doi ((cua tre) OR (cua te)).
• The words AND, OR and NOT may confuse the search; try adding quotes: "so sach ky nang xa hoi. hieu ((va cam) or (va cac)) tuc xa huong doi ((cua tre) OR (cua te))".
• Adding a wildcard symbol may retrieve word variants: so sach ky nang xa hoi. hieu ((va cam) or (va cac)) tuc xa huong doi ((cua tre) OR (cua te))*.
