 Searching for anything in Banfield, such as
 [http://nominatim.openstreetmap.org/search.php?q=Av+Alsina+950 Av Alsina
 950] ([http://nominatim.openstreetmap.org/details.php?place_id=5989203693
 place]), always returns the post code B1832AHQ (unless the object has an
 explicit addr:postcode of its own). According to taginfo, the only usage
 of the post code B1832AHQ is on a
 [http://openstreetmap.org/browse/way/170042601 certain building]
 ([http://nominatim.openstreetmap.org/details.php?place_id=91722766
 place]), but Nominatim seems to apply it to everything in
 [http://openstreetmap.org/browse/relation/2400639 Partido de Lomas de
 Zamora].

 For the case I quoted in Alsina 950, I would expect it to get the postcode
 from the enclosing [http://openstreetmap.org/browse/relation/2537834
 Banfield boundary relation].

 ([http://openstreetmap.org/browse/relation/2537834 Banfield] and
 [http://openstreetmap.org/browse/relation/2537822 Lomas de Zamora] are
 inside [http://openstreetmap.org/browse/relation/2400639 Partido de Lomas
 de Zamora])
