Perhaps you should try some spelling variations:
yang yang » wang yang, wang yan
one case » some case, one class, one phase
case das » case des, case case, case data
yang jie » yang jin, yang di, yang xi
yang jui » yang di, yang xi
das bin » das big, das bn, das bilan
yang yi » yang di, yang xi

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

• Performing a fuzzy search may retrieve terms with similar spellings: one case das bin we ((((yang jie) OR (yang yang))) OR (yang yi)) ((yang judy) OR (yang jui)) ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "one case das bin we ((((yang jie) OR (yang yang))) OR (yang yi)) ((yang judy) OR (yang jui)) ;*".
