Difference Between Local Nominatim and OpenStreetMap Website results

I have installed nominatim 4.1.0 (tokenizer= ICU) via following instructions on nominatim documentation, added wikipedia data during the installation, and imported an updated pbf file from geofabrik.de.

All works but when I sent some kind of request (e.g. Cagliari via Roma) the answer I get from Nominatim Website (https://nominatim.openstreetmap.org/) and my local installation are very different. The right results are on nominatim website of course.

The problems seems to be with the search candidate algorithm or the attribuition/calc of AdressImportance parameter. The very strange thing is that I get these wrong results only for some requests.

There is any particular parameter to set or anything else to verify?

I hope it is clear for you and even small advice or comment would be very helpful for me

Thanks Michele

After a discussion with the maintainers (https://github.com/osm-search/Nominatim/discussions/2839), I found an acceptable solution by editing the Geocode.php file line as follows:

$this->iLimit = $iLimit + max($iLimit, 150)

the result is not exactly the same as that of the online version but it works fine for me
