• If you are trying to use Boolean operators, they must be ALL CAPS: tu sach my ((va tay) OR (van tay)) hoi. hieu ((van cap) OR (van ca)) nuoc va danh va cau tren~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "tu sach my ((va tay) OR (van tay)) hoi. hieu ((van cap) or (van ca)) nuoc va danh va cau tren~".
• Adding a wildcard symbol may retrieve word variants: tu sach my ((va tay) OR (van tay)) hoi. hieu ((van cap) or (van ca)) nuoc va danh va cau tren*.
