Elasticsearch python API: Delete documents by query

I see that the following API will do delete by query in Elasticsearch - http://www.elasticsearch.org/guide/en/elasticsearch/reference/current/docs-delete-by-query.html

But I want to do the same with the elastic search bulk API, even though I could use bulk to upload docs using

es.bulk(body=json_batch)

I am not sure how to invoke delete by query using the python bulk API for Elastic search.

Seeing as how elasticsearch has deprecated the delete by query API. I created this python script using the bindings to do the same thing. First thing define an ES connection:

import elasticsearch
es = elasticsearch.Elasticsearch(['localhost'])

Now you can use that to create a query for results you want to delete.

search=es.search(
    q='The Query to ES.',
    index="*logstash-*",
    size=10,
    search_type="scan",
    scroll='5m',
)

Now you can scroll that query in a loop. Generate our request while we do it.

 while True:
    try: 
      # Git the next page of results. 
      scroll=es.scroll( scroll_id=search['_scroll_id'], scroll='5m', )
    # Since scroll throws an error catch it and break the loop. 
    except elasticsearch.exceptions.NotFoundError: 
      break 
    # We have results initialize the bulk variable. 
    bulk = ""
    for result in scroll['hits']['hits']:
      bulk = bulk + '{ "delete" : { "_index" : "' + str(result['_index']) + '", "_type" : "' + str(result['_type']) + '", "_id" : "' + str(result['_id']) + '" } }\n'
    # Finally do the deleting. 
    es.bulk( body=bulk )

To use the bulk api you need to ensure two things:

1. The document is identified You want to update. (index, type, id)
2. Each request is terminated with a newline or /n.
