• If you are trying to use Boolean operators, they must be ALL CAPS: ((((wang yong) OR (wang yan))) OR (wang yang)) wang hua gain sharing jin congo shu ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((((wang yong) OR (wang yan))) or (wang yang)) wang hua gain sharing jin congo shu ;~".
• Adding a wildcard symbol may retrieve word variants: ((((wang yong) OR (wang yan))) or (wang yang)) wang hua gain sharing jin congo shu ;*.
