Perhaps you should try some spelling variations:
fordern das » fordern als, fordern am, formen das
formen lam » formen im, formen a, formen ab
klang die » klang iii, klaue die
klang der » klarung der, gang der
david k » david a, david _
k hai » k hari, _ hai, k lai
qian » ian, kian, jian
rong » long, hong, pong

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: qian rong ((klang die) OR (klang der)) ((formen lam) OR (fordern das)) david k hai ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "qian rong ((klang die) OR (klang der)) ((formen lam) or (fordern das)) david k hai ;~".
• Adding a wildcard symbol may retrieve word variants: qian rong ((klang die) OR (klang der)) ((formen lam) or (fordern das)) david k hai ;*.
