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