Perhaps you should try some spelling variations:
fordern das » fordern als, fordern am, formen das
formen lam » formen im, formen a, formen ab
david dang » david ian, david mant, david ng
qian pong » qian wang
klang iii » klang die, zwang iii
rong » long, hong, ong
hai » hadi, haji, hari

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