This is my first ticket I ever submitted so please bear with me.

I not so recently ago (a year ago) tagged most Luxembourgish villages place tags with is_in tags to attribute each village with the right municipality. According to documentation, Nominatim makes use of is_in* tags, but when you search for a Lux village in Nominatim, Nominatim always return the village as part of Luxembourg only, it doesnt take into account the municipality.

Example is Rodenbourg, which belongs to Junglinster and is tagged as such [http://nominatim.openstreetmap.org/details.php?place_id=1030225] and OSM Node [http://www.openstreetmap.org/browse/node/289182356] . In Nominatim it comes out as belonging to Luxembourg...

Another example, where I changed the is_in tag to is_in:municipality with no effect:
[http://www.openstreetmap.org/browse/node/60844424] and corresponding Nominatim place page: [http://nominatim.openstreetmap.org/details.php?place_id=222886]

How can this be explained?

I'm unable to find any place or admin boundary called Junglinster (except the village).

In order to be linked the place / admin area has to be present in OSM data.

If Junglinster place is present and I've missed it please re-open with the node/way/relation id

So there needs to be an administrative boundary tagged as junglister for nominatim to recognize the hierarchy? Junglinster exists [http://nominatim.openstreetmap.org/details.php?place_id=239866] , how would I need to tag it to be recognized as both one of several villages forming a municipality, as well as the municipality itself by Nominatim ??!?!

It doesn't make sense for a village to be child of another village.

I would say that they are both children of a larger administrative area that shares the name of one of the villages. This is quite normal, although it more commonly occurs with cities.

See:

http://wiki.openstreetmap.org/wiki/Tag:boundary%3Dadministrative

OR

http://wiki.openstreetmap.org/wiki/Key:place

i.e. (find nearest equivalent)
place state node area state
place region node area region
place county node area county

and create a suitable administrative boundary or at least add a node roughly where the centre id.

Creating an area / boundary is always better if you have enough data to be able to draw it at least roughly.

Okay that clears things up a bit, I dont have access to the municipality boundaries, so will leave it at that for the moment

This was a problem in the OSM data not in Nominatim. Seems fixed now by a boundary import.
