Perhaps you should try some spelling variations:
neuen ansatzes » neuen ansatzen, neue ansatze, neueren ansatze
eu ansatzes » des ansatzes, news ansatzes, nis ansatzes
yang guang » yang yang, yan guan, yang liang
zhong zhi » zhang zhi, hong ghi, zhong tai
nan yang » dan yang, nan yan, tan yang
dong di » dong sin
im j » tim j, i j, m j

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: nan yang guang ((eu ansatzes) OR (neuen ansatzes)) im j ((zhong zhi) OR (dong di)) ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "nan yang guang ((eu ansatzes) OR (neuen ansatzes)) im j ((zhong zhi) or (dong di)) ;~".
• Adding a wildcard symbol may retrieve word variants: nan yang guang ((eu ansatzes) OR (neuen ansatzes)) im j ((zhong zhi) or (dong di)) ;*.
