How can I delete all documents in Elasticsearch from index without deleting index itself?
from elasticsearch import Elasticsearch
es = Elasticsearch("http://elasticsearch.internal:9200")
Elasticsearch.delete(es, index="index")
response
TypeError: delete() missing 1 required positional argument: 'id'
Is there option like truncate table in sql. I know that I can loop all ids and delete each of them but maybe there is some magic option with wildcard for example.
Elasticsearch.delete_by_query method can be used for deleting documents matching a query.
indices = ['index1', 'index2', 'other-index-names']
es.delete_by_query(index=indices, body={"query": {"match_all": {}}})
The elasticsearch.Elasticsearch.delete method is not a static method and should be called using an instance of elasticache.Elasticsearch, and this way self will automatically be passed as an argument to the delete method when it is called.
Example:
from elasticsearch import Elasticsearch
es = Elasticsearch()
Reference: https://elasticsearch-py.readthedocs.io/en/master/api.html#elasticsearch.Elasticsearch
Secondly, as described by the elastic search documentation here, "You use DELETE to remove a document from an index. You must specify the index name and document ID." Therefore, you should provide it both.
Example:
doc_id = "my_document"
my_index = "index"
es.delete(id=doc_id, index=my_index)
Reference: https://elasticsearch-py.readthedocs.io/en/master/api.html#elasticsearch.Elasticsearch.delete
