Perhaps you should try some spelling variations:
savings cross » savings groups, savings access, savings group
along what » along who, wrong what
wang ying » wang yang, wang jing, wang ning
wang yong » wang yang, wang hyoung, wang yan
oder cost » der cost, lower cost, power cost
jin oder » ein oder, sein oder, wien oder

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 ying) OR (wang yong)) jin oder cost savings cross ((along what) OR (log what)) ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((wang ying) OR (wang yong)) jin oder cost savings cross ((along what) or (log what)) ;~".
• Adding a wildcard symbol may retrieve word variants: ((wang ying) OR (wang yong)) jin oder cost savings cross ((along what) or (log what)) ;*.
