unable to query "created_by" tag with value "~OsmAnd.*"

[govvin]

I'm trying to find out how often OsmAnd is used for collecting POIs in a certain region [0]. I ran a query [1] using regex but it returns an empty result, although I know for a fact that POIs in the area exists as tag created_by=OsmAnd~ 2.1.1

Trying out a more generic query [1], using "created_by=*" produces results, but do not include those POIs with the value "OsmAnd~ 2.1.1".

Would this have to do with the tilde within the tag value?

The tag "created_by" you're referring to in [0] is part of the changeset metadata.

At this time, you can only query for nodes, ways, relations and areas, i.e. what you're trying to do is unfortunately impossible with Overpass API / overpass turbo. Both your examples [1] and [2] query for a tag created_by on the level node/way/relation. That's really something completely different!

There's already a GitHub ticket for your requirement. Please follow up there as needed: drolbr/Overpass-API#189
