Perhaps you should try some spelling variations:
reformen beim » reformen bei, reformen teil, reformen der
reformen im » reformen _, formen im, reformen der
yang yang » wang yang, wang yan
david ian » david a, david n
yang den » yang dean, gang der, yang di
david g » david a, david _, david k

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: yang yang yang den ((reformen beim) OR (reformen im)) ((david ian) OR (david g)) hai ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "yang yang yang den ((reformen beim) OR (reformen im)) ((david ian) or (david g)) hai ;~".
• Adding a wildcard symbol may retrieve word variants: yang yang yang den ((reformen beim) OR (reformen im)) ((david ian) or (david g)) hai ;*.
