• If you are trying to use Boolean operators, they must be ALL CAPS: tu sach y ((lang xa) OR (nang ma)) hoi. lieu ((va cam) OR (va cao)) cac ban danh va chua tre.
• The words AND, OR and NOT may confuse the search; try adding quotes: "tu sach y ((lang xa) or (nang ma)) hoi. lieu ((va cam) OR (va cao)) cac ban danh va chua tre".
• Adding a wildcard symbol may retrieve word variants: tu sach y ((lang xa) or (nang ma)) hoi. lieu ((va cam) OR (va cao)) cac ban danh va chua tre*.
