Perhaps you should try some spelling variations:
klarung der » klarung des, erklarung der, klang der
zwang iii » zugang iii, klang iii
yang dali » yang di, bang dai, yang all
yan wang » yuan wang, yang yang, qian wang
forme de » formes de, formen der, formen des
de david » die david, wade david, dawe david
david ng » david g, david n, david a
ng hai » dang hai, hong hai

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: yan wang ((((klarung der) OR (zwang iii))) OR (yang dali)) forme de david ng hai ;~.
• Adding a wildcard symbol may retrieve word variants: yan wang ((((klarung der) or (zwang iii))) or (yang dali)) forme de david ng hai ;*.
