• The words AND, OR and NOT may confuse the search; try adding quotes: "((su cac) OR (tu cac)) ky nang xa hoi. hieu van bao xuc ((va thanh) OR (ban thanh)) trinh cuu tre".
• Adding a wildcard symbol may retrieve word variants: ((su cac) OR (tu cac)) ky nang xa hoi. hieu van bao xuc ((va thanh) OR (ban thanh)) trinh cuu tre*.
