Perhaps you should try some spelling variations:
goals based » goal based
goals case » goals can, goals core, goals make
yan zwang » yan wang, yan zhang, yan liang
song thin » song shin, song jin, song min
wenn die » kann die
wang » wing, wan, lang
zwang » zwing, zwan, zlang

You may be able to get more results by adjusting your search query.

• If you are trying to use Boolean operators, they must be ALL CAPS: wang yan zwang ((goals case) OR (goals based)) thinking from ((wenn die) OR (song thin)) ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "wang yan zwang ((goals case) OR (goals based)) thinking from ((wenn die) or (song thin)) ;~".
• Adding a wildcard symbol may retrieve word variants: wang yan zwang ((goals case) OR (goals based)) thinking from ((wenn die) or (song thin)) ;*.
