Elastic search delete operation

问题:

Am new to elastic search and struggling to delete an entry from my collection. I need a query similar to this one DELETE FROM message WHERE id='1323'" and created_user = "user@gmail.com".

Following are my elastic search query, when i execute this, its only deleting the particular id field, its not taking the second argument created_user. Please help me to solve this issue. Thanks

var created = "9ed8afe738aa63c28b66994cef1f83c6"
db.delete({
            index: 'outboxpro',
            type: 'message',
            id: req.body.post_id,
            created_user: created
        }, function (error, resp) {
            if (error) {
                return next(error);
            }
            var data = {};
            console.log('delete response',resp);
            if (resp.hits.successful < 1) {
            data = {status: false, message: 'NO POST FOUND TO DELETE', code: 400};
            res.send(data);
            } else {
                return next({status: true, message: 'POST DELETED', data: error, code: 500});
            }
});

//// EDIT I have tried deleteByQuery, following are my code

db.deleteByQuery({
    index: 'outboxpro',
    type: 'message',
    body:{
        "query": {
            "filtered": {
                "query": {
                    "match": {
                        "_id": {
                            "query": "Kal4AXi5R9G-IMx4GIKYMw"
                        }
                    }
                },
                "filter": {
                    "and": [
                        {
                            "term": {
                                "created_user": created 
                            }
                        }
                    ]
                }
            }
        }
    }
}, function (error, resp) {
    if (error) {
        return next(error);
    }
    console.log('post deleted');
});

The delete API will do exactly what you want, just in a slightly round-about way.

What you'll have to do first is search for the documents you want to delete, so construct a search query that find all documents with the id of '1323' and a created_user of 'user@gmail.com'. From the returned documents you'll be able to retreive the document ID which you then need to pass through to the delete API.

You can delete documents matching your query, using delete by query in elasticsearch.. Refer

  db.deleteByQuery({
    index: 'outboxpro',
    type: 'message',
    body: {

        "query": {
            "filtered": {
                "query": {
                    "match": {
                        "_id": "Kal4AXi5R9G-IMx4GIKYMw"
                    }
                },
                "filter": {
                    "term": {
                        "created_user": "created"
                    }
                }
            }
        }
    },
    function (error, resp) {
        if (error) {
