Perhaps you should try some spelling variations:
iii reformen » die reformen, der reformen, und reformen
iii formen » die formen, iii form
beim david » kim david
david dang » david ian, david mant, david ng
yang yang » wang yang, wang yan
ii formen » ii normen, die formen, 2 formen
yang yan » wang yan, yang fan, yang yao

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: yang yang yan ((iii reformen) OR (((iii formen) OR (ii formen)))) beim david dang (hai OR hadi) ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "yang yang yan ((iii reformen) or (((iii formen) OR (ii formen)))) beim david dang (hai or hadi) ;~".
• Adding a wildcard symbol may retrieve word variants: yang yang yan ((iii reformen) or (((iii formen) OR (ii formen)))) beim david dang (hai or hadi) ;*.
