Perhaps you should try some spelling variations:
mappings using » mapping using, savings using
cost mappings » cost savings, case mapping, code mapping
ying anhang » sind anhang, ying chang, einem anhang
anhang ii » anhang i, anhang 1, anhang a
fan ying » fan xing, ran ying, tan ying
ii cost » ii cos, ii cross, di costo
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: fan ying anhang ii cost mappings using ((((dong sin) OR (dort ii))) OR (dong di)) ;~.
• Adding a wildcard symbol may retrieve word variants: fan ying anhang ii cost mappings using ((((dong sin) or (dort ii))) or (dong di)) ;*.
