Perhaps you should try some spelling variations:
fordern das » fordern als, fordern am, formen das
formen lam » formen im, formen a, formen ab
plan long » place long, plan loans, pain long
klang iii » zwang iii
klang die » klang der, klaue die
david n » david a, david _, david k
n hai » _ 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: plan long ((klang iii) OR (klang die)) ((formen lam) OR (fordern das)) david n hai ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "plan long ((klang iii) OR (klang die)) ((formen lam) or (fordern das)) david n hai ;~".
• Adding a wildcard symbol may retrieve word variants: plan long ((klang iii) OR (klang die)) ((formen lam) or (fordern das)) david n hai ;*.
