• The words AND, OR and NOT may confuse the search; try adding quotes: "((su can) OR (su van)) ky ((hang tai) or (dung tai)) roi. hieu ve cham luc va hanh thai cua tre~".
• Adding a wildcard symbol may retrieve word variants: ((su can) OR (su van)) ky ((hang tai) or (dung tai)) roi. hieu ve cham luc va hanh thai cua tre*.
