Perhaps you should try some spelling variations:
one agent » one parent, one event, und agent
wang das » wang dan, wang dashu, wang yan
das clan » das bilan, das land, das cern
one gene » gene gene, e gene, one get
can only » can one
many one » man one, many core, money one
clan a » plan a, clan _, alan a

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: wang das clan a ((one gene) OR (one agent)) ((can only) OR (many one)) saul ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "wang das clan a ((one gene) OR (one agent)) ((can only) or (many one)) saul ;~".
• Adding a wildcard symbol may retrieve word variants: wang das clan a ((one gene) OR (one agent)) ((can only) or (many one)) saul ;*.
