• If you are trying to use Boolean operators, they must be ALL CAPS: so sach thu tang van hoi. hieu vu kham duc va thanh ban ((cua tre) OR (((cuu tre) OR (cau treo))))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "so sach thu tang van hoi. hieu vu kham duc va thanh ban ((cua tre) or (((cuu tre) OR (cau treo))))~".
• Adding a wildcard symbol may retrieve word variants: so sach thu tang van hoi. hieu vu kham duc va thanh ban ((cua tre) or (((cuu tre) OR (cau treo))))*.
