• If you are trying to use Boolean operators, they must be ALL CAPS: toc sach xa nang ((lai hoi) OR (((dai hoi) OR (dai hai)))). lieu va nam thuoc va tang tai cuc tre~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "toc sach xa nang ((lai hoi) or (((dai hoi) OR (dai hai)))). lieu va nam thuoc va tang tai cuc tre~".
• Adding a wildcard symbol may retrieve word variants: toc sach xa nang ((lai hoi) or (((dai hoi) OR (dai hai)))). lieu va nam thuoc va tang tai cuc tre*.
