Perhaps you should try some spelling variations:
doing sin » dong sin, doing un
doing von » doing un, ing von
when gong » when songs, when good, when goal
gong min » jong min, song min, gong meng
yang yue » wang yue, yang yun, yang jui
dann ii » dann bin, daten ii
ii when » xxii when, ii where, ii wesen
yang yi » yang di, yang jui
yang xi » yang di, 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: ((doing sin) OR (doing von)) dann ii when gong min ((yang yue) OR (((yang yi) OR (yang xi)))) ;~.
• Adding a wildcard symbol may retrieve word variants: ((doing sin) or (doing von)) dann ii when gong min ((yang yue) or (((yang yi) or (yang xi)))) ;*.
