Perhaps you should try some spelling variations:
documentations » documentation, documentaries
argumentations » argumentation, argumentationen, augmentation
dokumentationen » documentation, dokumentationsband, dokumentarischen, documentationen
documentationen » documentation, documentationt, argumentationen
dokumentation » documentation

You may be able to get more results by adjusting your search query.

• Performing a fuzzy search may retrieve terms with similar spellings: (((documentations OR argumentations) or (dokumentationen or documentationen)) or dokumentation)~.
• If you are trying to use Boolean operators, they must be ALL CAPS: (((documentations OR argumentations) OR (dokumentationen OR documentationen)) OR dokumentation).
• The words AND, OR and NOT may confuse the search; try adding quotes: "(((documentations OR argumentations) or (dokumentationen or documentationen)) or dokumentation)".
• Adding a wildcard symbol may retrieve word variants: (((documentations OR argumentations) or (dokumentationen or documentationen)) or dokumentation)*.
