Perhaps you should try some spelling variations:
documentaries » documentation, documentary, commentaries
dokumentation » documentation
dokumentationen » documentationen, documentation, dokumentationsband, dokumentarischen
documentationen » documentation, documentations, argumentationen
documentationt » documentation, documentations, adocumentation

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

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