[OSM-talk] GeoJSON and TileMill

Hi.
I want to do some maps in TileMill and have a question.
As a data source for now I use GeoJSON exports from overpass-turbo,
which looks fine so far.

I can style that as long as I style everything (e.g. I exported all
highway=* in my target area and I'm able to draw lines for all
highways), but how can I query only specific tags in that layer?

It looks like tags are recognized as one field by tilemill, not as
individual fields/columns, so that a selector by field is not sufficient.
Is there anything I could do or is geojson support that limited?

regards
Peter
