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
ununmittelbareee » ununmittelbareeee, unununmittelbareee, ununermittelbareee, ununmittelbareren, ununmittelbare, ununmittelbaren, unmittelbare, unmittelbaren, unmittelbarer

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