Perhaps you should try some spelling variations:
does human » das human, does humanity, models human
des human » das human, des humains, des humanen
dong bin » dong di, dann bin
ya human » a human, das human, 2 human
gene yan » gene bank, ren yan, see yan
von sam » von sa, von sap, von scham
yan ji » yan jiu, ban ji, pan ji
ji von » ii von, ji won, si von
sin » sign, sind, skin

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: ((dong bin) OR (dong sin)) ((ya human) OR (((does human) OR (des human)))) gene yan ji von sam ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((dong bin) or (dong sin)) ((ya human) or (((does human) OR (des human)))) gene yan ji von sam ;~".
• Adding a wildcard symbol may retrieve word variants: ((dong bin) or (dong sin)) ((ya human) or (((does human) OR (des human)))) gene yan ji von sam ;*.
