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, yan guan, yang liang
nan yang » dan yang, nan yan, tan yang
hong hai » shang hai, zhong tai, dang hai
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 im j ((hong hai) OR (dong di)) ;~.
• Adding a wildcard symbol may retrieve word variants: nan yang guang eu ansatzes im j ((hong hai) or (dong di)) ;*.
