Perhaps you should try some spelling variations:
human bone » human bones, human body
human gene » human genome, human gender, human genetic
sitz kong » sing kong
kong guan » thong guan
yang jui » yang judy, yang yi
als sitz » als sinn
yang xi » yang yi
n 2 » nr 2

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

• If you are trying to use Boolean operators, they must be ALL CAPS: ((((yang jui) OR (yang xi))) OR (yang di))n 2 ((human gene) OR (human bone)) als sitz kong guan ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((((yang jui) or (yang xi))) or (yang di))n 2 ((human gene) OR (human bone)) als sitz kong guan ;~".
• Adding a wildcard symbol may retrieve word variants: ((((yang jui) or (yang xi))) or (yang di))n 2 ((human gene) OR (human bone)) als sitz kong guan ;*.
