Option to search for "city" in addr:city and addr:district at once

[bogatkaj]

Hey, I have the following problem:

I'm programming on a tool for disaster relief management at scene for the german speaking countries.
For Germany I'm having issues with an address in a smaller town.

The name of the town is "Nordkampen", which belongs to the city of Walsrode (and therefore the correct addr is Nordkampen 10, 29664 Walsrode), but is a so called "Ortschaft".

So in Germany you would rather say someone is from Nordkampen instead of from the district of Nordkampen in Walsrode.
So if someone searches for the address and types in Nordkampen as city, Nominatim doesn't returns a result.

Is there any option to set, to also search for the district?

Example urls:

City = Nordkampen:
http://nominatim.openstreetmap.org/search?street=Nordkampen%2011&city=Nordkampen&country=Deutschland&addressdetails=1&accept-language=de-DE&countrycodes=de&format=geocodejson&limit=1&layer=address&dedup=1

City = Walsrode:
http://nominatim.openstreetmap.org/search?street=Nordkampen%2011&city=Walsrode&country=Deutschland&addressdetails=1&accept-language=de-DE&countrycodes=de&format=geocodejson&limit=1&layer=address&dedup=1

If you have user-supplied input that is not supposed to be a strict address, I would advise against using form input and structured search. Just use a free-form field and people will likely just type 'nordkampen 11' in this case, which will work.

That said, 'nordkampen 11, nordkampen' really should get results as well. And if that works, the structured search would work as well. We already had the discussion in #2496, which I've now reopened.

Hey thanks for the response.
We have in fact a software form where the user enters the address in separate fields (street, number, ZIP, city), but as these info is often entered from verbally communicated info and / or under pressure, we can't assure complete correctness.
So the main reason for using nominatim is to get the coordinate of the entered address but also correcting the address if possible.

In personally would like to have some more optional parameters to define which fields are searched in which way (like a bool parameter to do two queries w. & w.o. the zip-code at once, as the zip sometimes leads to no or wrong results)

P.S.
The topic in 2496 is a bit different i guess, since, in this particular case, Nordkampen is in fact the street (and town) in the official address, so addr:place tag doesn't applies here according to the OSM wiki.

(For clarification on German: Das Ortsschild latutet "Nordkampen - Stadt Walsrode", die postalische Adresse in Nordkmapnen lautet durchgängig "Nordkampen X, 29664 Walsrode", sprich hier ist der Straßenname offiziell gegeben und somit die Nutzung von addr:place lt. OSM wiki nicht vorgesehen)

Even if you have separate fields in your form, you can still use the free-text query mode for Nominatim to get a bit more flexibility. Simply concatenate the fields using a comma. Make sure to keep proper "address order".

Postcodes and housenumbers are already optional to a certain degree. The behaviour here is hard-coded and cannot be configured.

If you want to try different version of converting your input in a query then you need to do this on the client side and simply send two queries.

I don't understand this statement. This is exactly the use-case for addr:place and also mapped that way. Addresses in the hamlet come out exactly right.
