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 der, klang iii, klaue die
david n » david a, david _, david k
n hai » _ hai
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 ((formen lam) OR (fordern das)) david n hai ;~.
• Adding a wildcard symbol may retrieve word variants: qian rong klang die ((formen lam) or (fordern das)) david n hai ;*.
