Perhaps you should try some spelling variations:
yang liang » wang liang, yan liang, yang yang
data gain » data main, data going, data gaps
wenn das » wenn die
can data » can tata, dan data, fan data
yang jie » yang jin, yang jui, yang xi
das can » das clan, ideas can, das cafe
hai » hadi, haji, hari

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

• Performing a fuzzy search may retrieve terms with similar spellings: wenn das can data gain ((yang liang) or (((yang jie) or (yang di)))) dang hai ;~.
• If you are trying to use Boolean operators, they must be ALL CAPS: wenn das can data gain ((yang liang) OR (((yang jie) OR (yang di)))) dang hai ;.
• Adding a wildcard symbol may retrieve word variants: wenn das can data gain ((yang liang) or (((yang jie) or (yang di)))) dang hai ;*.
