• The words AND, OR and NOT may confuse the search; try adding quotes: "wang ((yong yang) or (ying yang)) ((dali test) OR (davis test)) housing bank kong sar ;~".
• Adding a wildcard symbol may retrieve word variants: wang ((yong yang) or (ying yang)) ((dali test) OR (davis test)) housing bank kong sar ;*.
