Perhaps you should try some spelling variations:
costs mappings » costs savings, cross mapping
mappings using » mapping using, savings using
ying anhang » sind anhang, ying chang, einem anhang
ran ying » fan ying, tan ying, jin ying
anhang i » anhang 1, anhang a
i costs » 3 costs, 4 costs, d costs
dort ii » dort bin, dort hin

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: ran ying anhang i costs mappings using ((((dong sin) OR (dort ii))) OR (dong di)) ;~.
• Adding a wildcard symbol may retrieve word variants: ran ying anhang i costs mappings using ((((dong sin) or (dort ii))) or (dong di)) ;*.
