• If you are trying to use Boolean operators, they must be ALL CAPS: thuoc sach ky dang lai hoi. hieu va cam tuc va tinh ((dai cua) OR (((hai cua) OR (hoi cua)))) tre~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "thuoc sach ky dang lai hoi. hieu va cam tuc va tinh ((dai cua) or (((hai cua) OR (hoi cua)))) tre~".
• Adding a wildcard symbol may retrieve word variants: thuoc sach ky dang lai hoi. hieu va cam tuc va tinh ((dai cua) or (((hai cua) OR (hoi cua)))) tre*.
