Perhaps you should try some spelling variations:
studien der » studien des, studie der, studien uber
3 studien » 3 studies, i studien, 2.3 studien
mini hong » min hong, tin hong, amin hong
yang jui » yang judy, yang xi
yang yi » yang xi
e mini » _ mini, a mini, des mini
der e » der eg, der _
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 3 studien der e mini 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 3 studien der e mini 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 3 studien der e mini hong tan ;*".
