• If you are trying to use Boolean operators, they must be ALL CAPS: wang ((huang jing) OR (huang ying)) lands cost during risk ((how she) OR (how scale)) ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "wang ((huang jing) OR (huang ying)) lands cost during risk ((how she) or (how scale)) ;~".
• Adding a wildcard symbol may retrieve word variants: wang ((huang jing) OR (huang ying)) lands cost during risk ((how she) or (how scale)) ;*.
