Thanks Raud and Clinton.
Together, you answered all my question :slight_smile:

I tried to change the parent of a document, simply by reindexing it with
another parent.

How can this be? can two documents of the same type exist with the same
ID
if they have a different parent?

A child is assigned to a particular shard based on the parent ID. If
you change the parent, then it tries to index that doc on a new shard
(potentially, depending on which shard the new ID hashes to) but it
doesn't know that it has to delete the old version on the old shard.

You have to handle this one yourself.

Also, none of them is accessible by "get" now.

neither of the following returns any result:
curl -X GET
'http://localhost:9200/my_index/my_doctype/id1&routing=old_parent
curl -X GET
'http://localhost:9200/my_index/my_doctype/id1&routing=new_parent

That's because you're using '&' instead of '?'

If so, how do I delete one of them (the old_parent one...), but not the
other?
