Perhaps you should try some spelling variations:
explikation » explication, exploitation, exploration
explikationen » explicationen, exploitationen, explorationen, implikationen, explikativen
komplikationen » implikationen
applikationen » implikationen

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: (explikation OR (komplikationen OR (applikationen OR explikationen))).
• Adding a wildcard symbol may retrieve word variants: (explikation or (komplikationen or (applikationen or explikationen)))*.
