Perhaps you should try some spelling variations:
reformen beim » reformen bei, reformen im, reformen teil
iii reformen » die reformen, iii formen, der reformen
david mant » david ma, david malone, david martin
wang yang » wang liang, wang yanling
david ian » david a, david n
yang » ryang
yan » ryan

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