Perhaps you should try some spelling variations:
studien uber » studie uber, studien der, studien zur
2.3 studien » 2.2 studien, 2.3 student
yang jui » yang judy, yang xi
uber das » uber die, uber den
min hong » amin hong, tin hong, min hyoung
yang yi » yang xi
das min » das main, das mit, das amini
a 2.3 » a 3.3, b 2.3, _ 2.3
tan » than

You may be able to get more results by adjusting your search query.

• Performing a fuzzy search may retrieve terms with similar spellings: ((((((yang yi) OR (yang jui))) or (yang dean))) or (yang di))a 2.3 studien uber das min hong tan ;~.
• If you are trying to use Boolean operators, they must be ALL CAPS: ((((((yang yi) OR (yang jui))) OR (yang dean))) OR (yang di))a 2.3 studien uber das min hong tan ;*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((((((yang yi) OR (yang jui))) or (yang dean))) or (yang di))a 2.3 studien uber das min hong tan ;*".
