Delete by query, noob question

Hello Guys,
I'm using the new ELK version 2.3 and I installed the new plugin delete-by-query.
In the old version to delete by query is in this way:

curl -XDELETE 'http://localhost:9200/twitter/tweet/_query' -d '{
    "query" : {
        "term" : { "user" : "kimchy" }
    }
}'

But I don't know how to delete now, because in the manual say this:
DELETE /twitter/tweet/_query?q=user:kimchy

How add DELETE /twitter/tweet/_query?q=user:kimchy in my curl command?.

Thank you.

That's somehow the same thing.

curl -XDELETE 'http://localhost:9200/twitter/tweet/_query' -d '{
    "query" : {
        "term" : { "user" : "kimchy" }
    }
}'

is in SENSE Editor:

DELETE /twitter/tweet/_query
{
    "query" : {
        "term" : { "user" : "kimchy" }
    }
}

Understood , thank you !!
