Perhaps you should try some spelling variations:
komplikation » implikation
komplikationen » implikationen
replikation » replication
explikation » explication, exploitation, exploration
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 explikation) OR applikation) OR komplikationen).
• The words AND, OR and NOT may confuse the search; try adding quotes: "((((komplikation OR replikation) or explikation) or applikation) or komplikationen)".
• Adding a wildcard symbol may retrieve word variants: ((((komplikation OR replikation) or explikation) or applikation) or komplikationen)*.
