Perhaps you should try some spelling variations:
wang danning » wang yanling, wang daoping, wang yangming
des planung » des planungs, der planung, die planung
planung des » planung der
yang yue » wang yue, yang yun, yang jui
yang jin » yang jie, yang jun, ying jin
des data » das data, dhs data, dns data
data hai » data hub, data how, data hob

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 danning ((((yang yue) OR (yang jin))) OR (yang di)) des planung des data hai ;~.
• Adding a wildcard symbol may retrieve word variants: wang danning ((((yang yue) or (yang jin))) or (yang di)) des planung des data hai ;*.
