Nominatim query returns no result when searching with House number followed by postal code
I have setup nominatim in my server and its working fine but if I search a address with the following pattern its not returning any geocoding results:
city/street name/House No./postal code OR
city/street name/postal code/House No.
But returning result for same if I supply the post code before street name or or city.
city/postal code/street name/House No. OR
postal code/city/street name/House No.
For Example:
Working :
https://nominatim.openstreetmap.org/search.php?q=brussels+1000+allee+verte+10+&polygon_geojson=1&viewbox=
Not working:
https://nominatim.openstreetmap.org/search.php?q=brussels+allee+verte+10+1000&polygon_geojson=1&viewbox=
It would also be helpful if you can let me know what is the correct way to search. search and if i missing something.
Thanks
