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

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 (explikationen OR explicationen))).
• The words AND, OR and NOT may confuse the search; try adding quotes: "(explikation or (komplikationen or (explikationen OR explicationen)))".
• Adding a wildcard symbol may retrieve word variants: (explikation or (komplikationen or (explikationen OR explicationen)))*.
