Perhaps you should try some spelling variations:
things during » things using, things sharing, thing hiring
died cost » die cost, fixed cost, added cost
diet cost » die cost, direct cost, net cost
tan yong » tan hong, tan kong, tan yang
yong jin » yang jin, ying jin, song jin
dort ii » dort bin, dort hin
dong » doing, long, done

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: tan yong jin ((died cost) OR (diet cost)) things during ((dong sin) OR (dort ii)) ;~.
• Adding a wildcard symbol may retrieve word variants: tan yong jin ((died cost) or (diet cost)) things during ((dong sin) or (dort ii)) ;*.
