Perhaps you should try some spelling variations:
wang peng » wang zheng, wang yang, wang yong
peng wang » ping wang, peng liang, hong wang
iii gene » iii rene, iii gender, iii genome
ein kern » einem kern, im kern
ii kern » im kern, ii kein, iii kein
i gene » _ gene, a gene, e gene
ghi » nghi, ghia

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 peng wang ((i gene) OR (iii gene)) one ((ein kern) OR (ii kern)) ghi ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "wang peng wang ((i gene) or (iii gene)) one ((ein kern) OR (ii kern)) ghi ;~".
• Adding a wildcard symbol may retrieve word variants: wang peng wang ((i gene) or (iii gene)) one ((ein kern) OR (ii kern)) ghi ;*.
