Perhaps you should try some spelling variations:
john ngosong » john song
huang ying » huang jing, huang ting, huang yang
wang yang » wang yan, wang liang, wang yanling
huang bin » huang lin, huang jing, huang ting
yang mri » yang muxi, yang di, yang jui
und john » und johann
mri 2 » mri _, mri 1, mri a
2 und » _ und, i und

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: ((wang yang) OR (((huang bin) OR (huang ying)))) yang mri 2 und john ngosong (sau OR sabu) ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((wang yang) or (((huang bin) or (huang ying)))) yang mri 2 und john ngosong (sau OR sabu) ;~".
• Adding a wildcard symbol may retrieve word variants: ((wang yang) or (((huang bin) or (huang ying)))) yang mri 2 und john ngosong (sau OR sabu) ;*.
