Perhaps you should try some spelling variations:
neuen ansatzes » neuen ansatzen, neue ansatze, neueren ansatze
eu ansatzes » des ansatzes, news ansatzes, nis ansatzes
yan guang » yang guang, yan guan, gan guan
zhong tai » hong tan, hong hai, zhong zhi
nan yan » nan ya, wang yan, qian yan
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 yan guang ((eu ansatzes) OR (neuen ansatzes)) im j ((zhong tai) OR (dong di)) ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "nan yan guang ((eu ansatzes) OR (neuen ansatzes)) im j ((zhong tai) or (dong di)) ;~".
• Adding a wildcard symbol may retrieve word variants: nan yan guang ((eu ansatzes) OR (neuen ansatzes)) im j ((zhong tai) or (dong di)) ;*.
