Perhaps you should try some spelling variations:
dam rauch » das auch, im rauch
rauch der » auch der, braucht der, nach der
wang ning » wang jing, wang liang, wang yang
yang jin » yang jie, yang jun, ying jin
wong yue » wang yue, hong yu
big dam » big data, big deal, big dead
yang yi » yang di, yang xi, 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: one big dam rauch der ((((wang ning) OR (yang jin))) OR (yang judy)) ((wong yue) OR (yang yi)) ;~.
• Adding a wildcard symbol may retrieve word variants: one big dam rauch der ((((wang ning) or (yang jin))) or (yang judy)) ((wong yue) or (yang yi)) ;*.
