In Switzerland there is a state which covers (according to Nominatim) about 95% of the whole country (but is actually quite small). I don't know if this is actually a bug of Nominatim, but I couldn't see a possibility to change this just by tagging nodes/relations differently.

The strange thing is that the "state" entry found by Nominatim has the admin_level=100 (placing it at the bottom of the Nominatim's indexing hierarchy) even though it is recognized as a state and should thus be admin_level=4 or (according to Nominatim's development overview) admin_level=8:
http://nominatim.openstreetmap.org/details.php?place_id=539508

Nominatim also finds the administrative boundary which is correctly labeled admin_level=4 but does not depict the exclave of this state, which is present in the respective relation:
http://nominatim.openstreetmap.org/details.php?place_id=65435320

It would be interesting to know how these two problem arise and how to fix them since there are similar other problems in Switzerland.

Are you still able to reproduce the problem ?

The two provided links lead to objects which do not fit. Could you please update your examples ?

Thanks

Probably solved by the reimport of the Nominatim DB and the import of admin boundaries in Switzerland.
