Is there any way to list metadata(like id, filename etc.) about documents which belong to certain collection of Watson Discovery? There are some API methods which need document id (like "delete document" for example), so obviously there should be a way to get this id. However I was not able to find how to do it (neither via UI nor via API).

The query *.* will list all the documents in the collection.

At the time of this posting, using the following query should return 10 documents with all available metadata (replacing the appropriate values in <> with your collection-specific details):
