Perhaps you should try some spelling variations:
studien uber » studie uber, studien der, studien zur
ii studien » i studien, ii studies, 3 studien
yang jui » yang judy, yang yi
uber das » uber die, uber den
amt hong » amin hong, a hong, ma hong
yang xi » yang yi
das amt » das alte
a ii » a iii, i ii, _ ii
tan » than

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: ((((((yang jui) OR (yang xi))) OR (yang dean))) OR (yang di))a ii studien uber das amt hong tan ;~.
• Adding a wildcard symbol may retrieve word variants: ((((((yang jui) or (yang xi))) or (yang dean))) or (yang di))a ii studien uber das amt hong tan ;*.
