Perhaps you should try some spelling variations:
yong yang » dong yang, kyoung yang, yong phang
yang yang » wang yang, wang yan
ying yang » yin yang, ying chang, wang yang
iii gene » iii rene, iii gender, iii genome
gene we » gene w, gene one, gene set
ii kern » ii kein, ein kern, iii kein
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 ((((yong yang) OR (yang yang))) OR (ying yang)) iii gene we ((ii kern) OR (im kern)) ghi ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "wang ((((yong yang) OR (yang yang))) or (ying yang)) iii gene we ((ii kern) or (im kern)) ghi ;~".
• Adding a wildcard symbol may retrieve word variants: wang ((((yong yang) OR (yang yang))) or (ying yang)) iii gene we ((ii kern) or (im kern)) ghi ;*.
