• If you are trying to use Boolean operators, they must be ALL CAPS: ((wang yong) OR (wang yang)) yang davis ((test housing) OR (era housing)) a kong saur ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((wang yong) OR (wang yang)) yang davis ((test housing) or (era housing)) a kong saur ;~".
• Adding a wildcard symbol may retrieve word variants: ((wang yong) OR (wang yang)) yang davis ((test housing) or (era housing)) a kong saur ;*.
