Perhaps you should try some spelling variations:
cost sharing » risk sharing, cost savings
und losung » und losungen, und auflosung
long iran » long grain, long run, long han
iran cost » urban cost, iran case, can cost
yan long » yan cong, van long, pain long
und long » und lohne, und lohn, und lock
wang » wing, lang

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: (wang OR wan) yan long iran cost sharing ((und long) OR (und losung)) ago ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "(wang or wan) yan long iran cost sharing ((und long) OR (und losung)) ago ;~".
• Adding a wildcard symbol may retrieve word variants: (wang or wan) yan long iran cost sharing ((und long) OR (und losung)) ago ;*.
