Perhaps you should try some spelling variations:
komplikation » komplikationen, implikation, replikation
explikation » explication, exploitation, explanation
explikationen » explicationen, exploitationen, explanationen, implikationen, applikationen, explorationen
applikation » application, applikationen

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