The documentation for _delete_by_query states that:
Elasticsearch will also create a record of this task as a document at
.tasks/task/${taskId}
. This is yours to keep or remove as you see fit. When you are done with it, delete it so Elasticsearch can reclaim the space it uses.
I have a task id that I can query via GET _tasks/. I do not have a .tasks index. Is the documentation wrong or am I looking in the wrong place? Where do I find this document in order to delete it?
