[OSM-dev] Overpass filter by area A or area B

[Jo]

You could also do this:

[maxsize:400000000];
(
way["wikidata"="Q212429"][admin_level=3];
way["wikidata"="Q212582"][admin_level=3];
)
._>;
out geom;

No need to store it in placeholders if you only want to join.

>> would give all ways contained in area_1 and area_2 as results.

>> Is this possible ?
