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