• If you are trying to use Boolean operators, they must be ALL CAPS: wang yang xi hua (rent OR test) ((yang li) OR (yang lin)) ((hong shu) OR (hong yu)) ;.
• The words AND, OR and NOT may confuse the search; try adding quotes: "wang yang xi hua (rent or test) ((yang li) OR (yang lin)) ((hong shu) or (hong yu)) ;".
