Perhaps you should try some spelling variations:
things during » things sharing, thing hiring, things turn
things using » settings using, savings using, ethics using
der solange » der solinger, der lange, der klange
die smart » der smart
dong sign » dong sin, among sign, dong bin
dann bin » dong bin
gang » lang, wang, yang

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: gang der solange die smart ((things using) OR (things during)) ((dann bin) OR (dong sign)) ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "gang der solange die smart ((things using) OR (things during)) ((dann bin) or (dong sign)) ;~".
• Adding a wildcard symbol may retrieve word variants: gang der solange die smart ((things using) OR (things during)) ((dann bin) or (dong sign)) ;*.
