Perhaps you should try some spelling variations:
yang guang » yang yang, yan guan, yang liang
3.2 andere » 1.2 andere, 4.2 andere, 3 andere
wang yang » wang yan, wang liang, wang yanling
andere do » andere der, andere das, andere die
tuan hua » tan hua, tuan vu, yuan hui
pei yang » wei yang, hui yang, yi yang
pei yun » lei kyun, mei yung, wei yuan

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 (yang guang)) ((tuan hua) OR (wang hua)) ((pei yang) OR (pei yun)) 3.2 andere do ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((wang yang) or (yang guang)) ((tuan hua) or (wang hua)) ((pei yang) OR (pei yun)) 3.2 andere do ;~".
• Adding a wildcard symbol may retrieve word variants: ((wang yang) or (yang guang)) ((tuan hua) or (wang hua)) ((pei yang) OR (pei yun)) 3.2 andere do ;*.
