Perhaps you should try some spelling variations:
child does » china does
yan liang » yang liang, wang liang, you liang
child der » child did, child gender
du langer » fur langer, 3 langer
yan guan » gan guan, yan yuan, yang guang
klang du » klang der, klang die, klang sdn
langer a » longer a, lander a, langer _

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: ((yan liang) OR (yan guan)) calle ((child der) OR (child does)) klang du langer a ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((yan liang) or (yan guan)) calle ((child der) OR (child does)) klang du langer a ;~".
• Adding a wildcard symbol may retrieve word variants: ((yan liang) or (yan guan)) calle ((child der) OR (child does)) klang du langer a ;*.
