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