I would like to extract, with Overpass Turbo, all members of a specific route relation that do not have a specific key (in my case, all ways that lack a surface tag).

We had the exact same question in the German forum thread "OverpassTurbo for Dummies" .

Here's how query should look like. Please adjust the relation id selection as needed.

relation(398874);way(r)[surface!~"."];out;>;out skel;

Try it in Overpass Turbo:

that's great - I often thought about the same! … And how to get a refinement of this? e.g. only tracks when searching for existence of tracktype? ;-) I tried relation(398874);way(r)["highway"="track"][tracktype!~"."];out;>;out skel; but that runs much much longer (until I cancel).

That's also possible with QL, but the query needs to be rewritten a bit due to a very expensive evaluation sequence:

relation(398874);way(r);way._["highway"="track"][tracktype!~"."];out;>;out skel;

great, thanks! I think this kind of refinement is often useful for those queries. I need to learn this language! :-)
