Deleting A document from a Index[]

Hello,
I want to delete a specific document from an Index how can I do that?
Thanks.

Call:

DELETE index/doc/id

Like:

PUT index/doc/1
{
  "foo": "bar"
}
DELETE index/doc/1

I know the index but I don't know the doc and id.
How to get that details?
Thanks.

What do you know about the document?

May you are looking for the delete by query feature?
