Perhaps you should try some spelling variations:
ansatzes im » ansatze im, ansatzes 2, ansatzes 3
ansatz im » ansatze im, ansatz ii, ansatz 2
zhong tai » hong tan, hong hai, zhong zhi
yan guan » gan guan, yan yuan, yang guang
tan yan » tan yang, nan yan, tan tan
guan eu » guang eu
dong di » dong sin

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: tan yan guan eu ((ansatzes im) OR (ansatz im)) j ((zhong tai) OR (dong di)) ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "tan yan guan eu ((ansatzes im) OR (ansatz im)) j ((zhong tai) or (dong di)) ;~".
• Adding a wildcard symbol may retrieve word variants: tan yan guan eu ((ansatzes im) OR (ansatz im)) j ((zhong tai) or (dong di)) ;*.
