You cannot expect the same results for your installation
as on the nominatim.openstreetmap website. The OSM server runs
always the latest version of Nominatim together with continuous
data update. That means that the data you see is indexed with
the Nominatim version that was current at the time it was last
touched.

I've tried with an import using latest Nominatim and also
updated the data on nominatim.osm.org. 'Slowik' appears in the
address in all cases. Can you check if you have 'Slowik' at all
in your database. If it is there, is it shown as being in
'gmina Zgierz'?
