Perhaps you should try some spelling variations:

formen lam » formen im, formen a, formen ab
klang iii » klang die
zwang iii » zugang iii
ian rong » qian rong, ian don, ma rong
david n » david a, david _, david k
n hai » _ hai

You may be able to get more results by adjusting your search query.

• Performing a fuzzy search may retrieve terms with similar spellings: ian rong ((klang iii) OR (zwang iii)) ((formen lam) or (fordern das)) david n hai ;~.
• If you are trying to use Boolean operators, they must be ALL CAPS: ian rong ((klang iii) OR (zwang iii)) ((formen lam) OR (fordern das)) david n hai ;*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "ian rong ((klang iii) OR (zwang iii)) ((formen lam) or (fordern das)) david n hai ;*".
