Perhaps you should try some spelling variations:
cost ratings » cost savings, costs savings, risk ratings
bond ratings » bond trading
risk bearing » risk sharing, risk taking, risk rating
bearing what » learning what, bring what, reading what
kant oder » kunst oder
wing yan » wang yan, wing ian, wing tan
kann » ann

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: wing yan ((kant oder) OR (kann die)) ((cost ratings) OR (bond ratings)) risk bearing what ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "wing yan ((kant oder) or (kann die)) ((cost ratings) OR (bond ratings)) risk bearing what ;~".
• Adding a wildcard symbol may retrieve word variants: wing yan ((kant oder) or (kann die)) ((cost ratings) OR (bond ratings)) risk bearing what ;*.
