• If you are trying to use Boolean operators, they must be ALL CAPS: te sach v nang cao hoi. lieu va ((cham xuc) OR (cham soc)) ((va hanh) OR (van hanh)) hai cua tre.
• The words AND, OR and NOT may confuse the search; try adding quotes: "te sach v nang cao hoi. lieu va ((cham xuc) or (cham soc)) ((va hanh) OR (van hanh)) hai cua tre".
