Perhaps you should try some spelling variations:
eu ansatzes » des ansatzes, neuen ansatzes, news ansatzes
ansatzes im » ansatze im, ansatz im, ansatzes 2
yang guang » yang yang, yang liang
zhong tai » hong tan, hong hai, zhong zhi
yan guan » gan guan, yan yuan, yihan guan
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: dan ((yang guang) OR (yan guan)) eu ansatzes im j ((zhong tai) OR (dong di)) ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "dan ((yang guang) OR (yan guan)) eu ansatzes im j ((zhong tai) or (dong di)) ;~".
• Adding a wildcard symbol may retrieve word variants: dan ((yang guang) OR (yan guan)) eu ansatzes im j ((zhong tai) or (dong di)) ;*.
