[Geocoding] Different result in local nominatim instance and official instance

[Bartosz Kwapisz]

I had the same result when I used 3.4.2, 3.5.2 and the master version.
That's why I thought the problem was in data.
We run nominatim in container environment, so we are using this
configuration (without any changes) -
https://github.com/mediagis/nominatim-docker/tree/master/3.5
You can find local.php file here -
https://github.com/mediagis/nominatim-docker/blob/master/3.5/local.php
That postgres and postgis packages are installed (in Dockerfile) -
postgresql-server-dev-12 postgresql-12-postgis-3 postgresql-contrib
postgresql-12-postgis-3-scripts \

I've pulled docker image based on nominatim master version that we are
using now to Docker Hub registry -
https://hub.docker.com/repository/docker/bartoliniii/nominatim

Tu run import we run the following sequence of commands:
apt-get -y update -qq
apt-get install -y wget
wget -q https://www.nominatim.org/data/wikipedia_article.sql.bin -O
/app/src/data/wikipedia_article.sql.bin
wget -q https://www.nominatim.org/data/wikipedia_redirect.sql.bin -O
/app/src/data/wikipedia_redirect.sql.bin
rm -rf /data/nominatim/postgresdata_updated2 && chmod u+x /app/init.sh
/app/init.sh /data-osm/osm-pbf/poland-latest.osm.pbf nominatim/postgresdata
