Perhaps you should try some spelling variations:
costs mappings » costs savings, cross mapping
mappings using » mapping using, savings using
fan ying » fan xing, ran ying, tan ying
klausa d » klausa die, klaus f, klaus w
dort bin » dort hin, dong bin, dort von
d costs » id costs, 3 costs, 4 costs
dort ii » dort hin
dong di » dong sin

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 klausa d costs mappings using ((((dort bin) OR (dort ii))) OR (dong di)) ;~.
• Adding a wildcard symbol may retrieve word variants: fan ying klausa d costs mappings using ((((dort bin) or (dort ii))) or (dong di)) ;*.
