• The words AND, OR and NOT may confuse the search; try adding quotes: "wang yang qiang ((als case) OR (als care)) thinking john ((bonn shin) or (song shin)) ;~".
• Adding a wildcard symbol may retrieve word variants: wang yang qiang ((als case) OR (als care)) thinking john ((bonn shin) or (song shin)) ;*.
