• If you are trying to use Boolean operators, they must be ALL CAPS: wang ((dong yang) OR (wang yang)) ((hua rein) OR (a rein)) yan jiu yong sar ;.
• The words AND, OR and NOT may confuse the search; try adding quotes: "wang ((dong yang) or (wang yang)) ((hua rein) OR (a rein)) yan jiu yong sar ;".
