Perhaps you should try some spelling variations:
states during » rates during, states making, strategies during
states using » rates using, estimates using, studies using
ying yang » yang yang, yin yang, ying chang
yang eine » yang jie, yang jin, yang jing
eine art » fine art, fine arts, eine auf
yu fang » yu gang, yu wang, yu yang

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

• Performing a fuzzy search may retrieve terms with similar spellings: ((ying yang) or (yu fang)) yang eine art ((states using) OR (states during)) dhm bei ;~.
• If you are trying to use Boolean operators, they must be ALL CAPS: ((ying yang) OR (yu fang)) yang eine art ((states using) OR (states during)) dhm bei ;*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((ying yang) or (yu fang)) yang eine art ((states using) OR (states during)) dhm bei ;*".
