• If you are trying to use Boolean operators, they must be ALL CAPS: ((su cach) OR (su cac)) tu nano 1 ha. hieu ve cham xuc va hanh vi ((cua triet) OR (cua viet)).
• The words AND, OR and NOT may confuse the search; try adding quotes: "((su cach) OR (su cac)) tu nano 1 ha. hieu ve cham xuc va hanh vi ((cua triet) or (cua viet))".
