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