• If you are trying to use Boolean operators, they must be ALL CAPS: ((so sach) OR (bo sach)) ky dong hoa hoi. hieu tu cham vuc van ((thanh va) OR (nhanh ha)) cua tre~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((so sach) OR (bo sach)) ky dong hoa hoi. hieu tu cham vuc van ((thanh va) or (nhanh ha)) cua tre~".
• Adding a wildcard symbol may retrieve word variants: ((so sach) OR (bo sach)) ky dong hoa hoi. hieu tu cham vuc van ((thanh va) or (nhanh ha)) cua tre*.
