Is there any possibility to delete documents from a watson discovery collection by date.
Something I would do in a SQL database like this:
DELETE FROM collection_name
WHERE publication_date < 2018-01-01;
I know, I can delete single documents by name and I could query the documents with a publication_date filer and after querying I could iterate over the document names and delete every single document but this seems a rather annoying approach for a quite simple task.
@user3609367 there is no way to delete multiple documents with a single API call. The approach you have mentioned in your post is the best way to do what you are asking.
