Perhaps you should try some spelling variations:
news ansatzes » des ansatzes, nis ansatzes, eines ansatzes
guang news » huang new
ansatzes 2 » ansatze 2, ansatze _, ansatze 3
zhong tai » hong tan, hong hai, zhong zhi
nan yang » dan yang, nan yan, wang yang
tan yang » dan yang, tan ying, tan yong
dong di » dong sin
2 j » 2 ja, 72 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) OR (tan yang)) guang news ansatzes 2 j ((zhong tai) OR (dong di)) ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((nan yang) OR (tan yang)) guang news ansatzes 2 j ((zhong tai) or (dong di)) ;~".
• Adding a wildcard symbol may retrieve word variants: ((nan yang) OR (tan yang)) guang news ansatzes 2 j ((zhong tai) or (dong di)) ;*.
