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