Perhaps you should try some spelling variations:
explikation » explication, exploitation, explanation
explikationen » explicationen, exploitationen, explanationen, implikationen, applikationen, explorationen
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 exploration) OR (komplikationen OR (explikationen OR explicationen))).
• The words AND, OR and NOT may confuse the search; try adding quotes: "((explikation OR exploration) or (komplikationen or (explikationen or explicationen)))".
• Adding a wildcard symbol may retrieve word variants: ((explikation OR exploration) or (komplikationen or (explikationen or explicationen)))*.
