Perhaps you should try some spelling variations:
mittelbar » mittelbare, unmittelbar, ermittelbar
unermittelbaree » unermittelbareee, unerunmittelbaree, unerermittelbaree, unvermittelbare, unmittelbare, unmittelbaren
unmittelbareee » unmittelbareeee, ununmittelbareee, unermittelbareee, unmittelbareren, unmittelbare, unmittelbaren
unmittelbareeee » unmittelbareeeee, ununmittelbareeee, unermittelbareeee, unmittelbarerene, unmittelbaree, unmittelbarene, unmittelbareren, unmittelbare, unmittelbaren

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: (mittelbar OR ((unermittelbaree OR (unmittelbareee OR unmittelbareeee)) OR (unmittelbareee OR unmittelbareeee))).
• The words AND, OR and NOT may confuse the search; try adding quotes: "(mittelbar or ((unermittelbaree or (unmittelbareee OR unmittelbareeee)) or (unmittelbareee OR unmittelbareeee)))".
• Adding a wildcard symbol may retrieve word variants: (mittelbar or ((unermittelbaree or (unmittelbareee OR unmittelbareeee)) or (unmittelbareee OR unmittelbareeee)))*.
