• If you are trying to use Boolean operators, they must be ALL CAPS: ((vu khach) OR (so sach)) ky dang van hoi. lieu va cham xuc va hanh vi ((cua triet) OR (va triet)).
• The words AND, OR and NOT may confuse the search; try adding quotes: "((vu khach) or (so sach)) ky dang van hoi. lieu va cham xuc va hanh vi ((cua triet) OR (va triet))".
