Perhaps you should try some spelling variations:
bonus cases » bonus shares
cases what » causes what, case what, crises what
what goal » what goals, what global, what goes
doing un » doing und, doing our, doing von
un bonus » can bonus, und bonum, von bonus
goal min » goal link, goal fig
yang jie » yang jin, yang jui, yang jun
yang xi » yang jui
yang yi » yang jui

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: doing un bonus cases what goal min ((((yang jie) OR (yang xi))) OR (((yang di) OR (yang yi)))) ;~.
• Adding a wildcard symbol may retrieve word variants: doing un bonus cases what goal min ((((yang jie) or (yang xi))) or (((yang di) or (yang yi)))) ;*.
