• If you are trying to use Boolean operators, they must be ALL CAPS: ((su sach) OR (so sach)) ky anh cay co. hieu va cac duc tan lang phi ((cua viet) OR (ca viet))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((su sach) OR (so sach)) ky anh cay co. hieu va cac duc tan lang phi ((cua viet) or (ca viet))~".
• Adding a wildcard symbol may retrieve word variants: ((su sach) OR (so sach)) ky anh cay co. hieu va cac duc tan lang phi ((cua viet) or (ca viet))*.
