• If you are trying to use Boolean operators, they must be ALL CAPS: su sach ky ((lang ha) OR (nang hoa)) hoi. lieu va cham xuc ban ((hang dien) OR (nhan dien)) cua tre.
• The words AND, OR and NOT may confuse the search; try adding quotes: "su sach ky ((lang ha) or (nang hoa)) hoi. lieu va cham xuc ban ((hang dien) OR (nhan dien)) cua tre".
• Adding a wildcard symbol may retrieve word variants: su sach ky ((lang ha) or (nang hoa)) hoi. lieu va cham xuc ban ((hang dien) OR (nhan dien)) cua tre*.
