• If you are trying to use Boolean operators, they must be ALL CAPS: ((dong sin) OR (((wang liang) OR (((yang yang) OR (wang yan)))))) a a test yan jiu long shu ;.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((dong sin) or (((wang liang) or (((yang yang) OR (wang yan)))))) a a test yan jiu long shu ;".
• Adding a wildcard symbol may retrieve word variants: ((dong sin) or (((wang liang) or (((yang yang) OR (wang yan)))))) a a test yan jiu long shu ;*.
