Perhaps you should try some spelling variations:
experimentiert » experimentieren, experimentierens, experimenting
experimentierte » experimentierene, experimentierense, experimentinge, experimentieren, experimentier, experimentierfeld
experimentierene » experimentierende, experimentieren, experimentierens
experimentierense » experimentierens, experimentierende, experimentierenden

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: ( experimentiert OR ((experimentierte OR experimentierene) OR experimentierense) ).
• The words AND, OR and NOT may confuse the search; try adding quotes: "( experimentiert or ((experimentierte OR experimentierene) or experimentierense) )".
• Adding a wildcard symbol may retrieve word variants: ( experimentiert or ((experimentierte OR experimentierene) or experimentierense) )*.
