Perhaps you should try some spelling variations:
komplikation » implikation, explikation
komplikationen » implikationen, explikationen
replikation » replication, explikation
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 replikation) OR exploration) OR applikation) OR komplikationen).
• Adding a wildcard symbol may retrieve word variants: ((((komplikation or replikation) or exploration) or applikation) or komplikationen)*.
