• If you are trying to use Boolean operators, they must be ALL CAPS: su ((((sach ky) OR (sach kem))) OR (sach y)) lang xa hoi. hieu va cham xuc va hanh vi so viet*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "su ((((sach ky) OR (sach kem))) or (sach y)) lang xa hoi. hieu va cham xuc va hanh vi so viet*".
