[Geocoding] Bbox option on Nominatim

[Rodolphe Quiédeville]

Hi,

This is my first post on this mailing list, so I'll try to present
myself a little bit. I'm a french DevOps usins OSM for myself and for my
customers, I'm working as freelance and do some DevOps tasks and a
little bit of developpement. My experience in PHP is more than 14 years,
I'll do also some python, perl and erlang too, I well known Debian and
GNU/Linux systems.

So if I write here it's because I maintain a nominatim serveur for
geocoding on a bbox that covers Europe, so I loaded it with an export
from geofabrik (thanks to them) and now run hourly update on it. If I
well understood, the update process load worlwide datas in the database,
so I propose to add an option --bbox to Nominatim to filter the
changes. The option will have the same structure as osm2pgsql and the
value will be set on osm2pgsql command line using it's option '-b'.

Before doing the patch, I wanted to discuss it about you, what do you
think about and have you some hints ?

Best regards,

PS : I've already found the Github repo of Nominatim and done a first PR
on the munin plugin nominatim_importlag, my nick on github is 'rodo'.
