Deletes an existing index under a collection.
The following request deletes the index called my-index under collection
my-namespace:my-collection
DELETE /my-namespace:my-collection/_index/my-index

Delete an existing collection.
The following request deletes the collection called my-collection:
DELETE my-collection
DELETE /[<namespace>:]<name>
<namespace><name>Delete an existing namespace.
The following request delete the namespace called website:
DELETE /_namespace/website
DELETE /_namespace/<name>
/_ns/<name> is accepted as a shorter alias.
<name>{ "acknowledged": true }
Deleting a namespace moves the WHOLE namespace into the trash: every
collection’s data directory is retained under <data_path>/trash/
together with a namespace-level restore snapshot (one snapshot per
collection — schemas, shard UUIDs, partition routing, placements). The
sweeper physically deletes it after trash.retention_secs.
Physically delete one trash item on every node that still holds it, without waiting for the retention window. This cannot be undone.
POST /_cluster/trash/1788916375_namespace-website/delete
{ "deleted": true, "item": "1788916375_namespace-website", "nodes": 2 }
POST /_cluster/trash/<item>/delete
<item>Physically delete every trashed item on every node, without waiting for the retention window. This cannot be undone.
POST /_cluster/trash/empty
{ "nodes": 2, "removed": 5 }
POST /_cluster/trash/empty
Delete a specific document from the specified collection by specifying its unique identifier.
Delete the document 0,0 from collection my-collection:
DELETE /my-collection/_doc/0,0
The API returns the following result:
{
"_id": "0,0",
"_version": 0,
"result": "deleted",
...
}
Deleting a document again (or fetching it after deletion) answers
404 with "result": "not_found" — the delete itself still succeeds
and reports "result": "deleted" only for a document that was live.
