Perhaps you should try some spelling variations:
case first » come first, cree first, gate first
things era » things here, things were, things a
yang faso » yang fan, yang yao
faso case » base case, case case, faso cote
tan yang » dan yang, tan ying, tan yong
dort bin » dort hin, dort von, org bin
dong bin » dong sin, dann bin
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: tan yang faso case first things era ((((dort bin) OR (dort ii))) OR (((dong di) OR (dong bin)))) ;~.
• Adding a wildcard symbol may retrieve word variants: tan yang faso case first things era ((((dort bin) or (dort ii))) or (((dong di) or (dong bin)))) ;*.
