Perhaps you should try some spelling variations:
komplikation » applikation, replikation
komplikationen » applikationen, replikationen, implikationen
implikation » implication, implikationen, implications
explikation » explication, exploitation, exploration

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