Perhaps you should try some spelling variations:
explikation » exploitation, exploration, explanation
explication » exploitation, application, exploration
explicationen » exploitationen, applicationen, explorationen, explicatione, explicationem, explikationen
komplikationen » implikationen
explorationen » exploration, explorations, explorativen

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