Perhaps you should try some spelling variations:
wang dan » wang yan, wang yidan, wang yang
wang ban » wang yan, wang yang, bang bang
irene um » irene m, ironie um, sirene im
die wang » die wand, die wahl, die wage
wang yue » wong yue, wang hua, wang yan
dn data » dan data, n data, own data
yang yi » yang xi, yang jui

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: ((dn data) OR (((wang dan) OR (wang ban)))) ((yang yi) OR (yang di)) irene um die wang yue ;~.
• Adding a wildcard symbol may retrieve word variants: ((dn data) or (((wang dan) or (wang ban)))) ((yang yi) or (yang di)) irene um die wang yue ;*.
