Elasticsearch : How to delete an Index using python

Question

Forgive me if this is quite basic but I have Python 2.7 and Elasticsearch 2.1.1 and I am just trying to delete an index using

es.delete(index='researchtest', doc_type='test') 

but this gives me

return func(*args, params=params, **kwargs) TypeError: delete() takes at least 4 arguments (4 given) 

I also tried

es.delete_by_query(index='researchtest', doc_type='test',body='{"query":{"match_all":{}}}') 

but I get

AttributeError: 'Elasticsearch' object has no attribute 'delete_by_query' 

Any idea why? Has the api changed for 2.1.1 for python?

Answer 1

From the docs, use this notation:

from elasticsearch import Elasticsearch es = Elasticsearch()  es.indices.delete(index='test-index', ignore=[400, 404]) 

Answer 2

If you have a document object (model) and you're using elasticsearch-dsl, specially with Python-3.X you can directly call the delete method of your model's _index attribute.

ClassName._index.delete() 

Also as it's stated in documentation:

The _index attribute is also home to the load_mappings method which will update the mapping on the Index from elasticsearch. This is very useful if you use dynamic mappings and want the class to be aware of those fields (for example if you wish the Date fields to be properly (de)serialized):

Post._index.load_mappings()
