Perhaps you should try some spelling variations:
human gender » bhutan gender, human gene, german gender
gender age » gender wage, under age, gender a
sinn kong » sing kong, king kong, ming kong
kong guan » thong guan
age sinn » tage sind, als sinn
yang yi » yang xi, yang jui
nr 2 » nr 1

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 judy) OR (yang yi))) OR (yang di))((n 2) OR (nr 2)) human gender age sinn kong guan ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((((yang judy) or (yang yi))) or (yang di))((n 2) OR (nr 2)) human gender age sinn kong guan ;~".
• Adding a wildcard symbol may retrieve word variants: ((((yang judy) or (yang yi))) or (yang di))((n 2) OR (nr 2)) human gender age sinn kong guan ;*.
