• If you are trying to use Boolean operators, they must be ALL CAPS: wang yang yi hua brain ((gong min) OR (song min)) ((hyoung ghi) OR (hyoung gun)) ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "wang yang yi hua brain ((gong min) or (song min)) ((hyoung ghi) OR (hyoung gun)) ;~".
• Adding a wildcard symbol may retrieve word variants: wang yang yi hua brain ((gong min) or (song min)) ((hyoung ghi) OR (hyoung gun)) ;*.
