API Documentation

All the API calls map the raw REST api as closely as possible, including the distinction between required and optional arguments to the calls. This means that the code makes distinction between positional and keyword arguments; we, however, recommend that people use keyword arguments for all calls for consistency and safety.

Note

for compatibility with the Python ecosystem we use from_ instead of from and doc_type instead of type as parameter names.

Global options

Some parameters are added by the client itself and can be used in all API calls.

Ignore

An API call is considered successful (and will return a response) if elasticsearch returns a 2XX response. Otherwise an instance of :class:`~elasticsearch.TransportError` (or a more specific subclass) will be raised. You can see other exception and error states in :ref:`exceptions`. If you do not wish an exception to be raised you can always pass in an ignore parameter with either a single status code that should be ignored or a list of them:

from elasticsearch import Elasticsearch
es = Elasticsearch()

# ignore 400 cause by IndexAlreadyExistsException when creating an index
es.indices.create(index='test-index', ignore=400)

# ignore 404 and 400
es.indices.delete(index='test-index', ignore=[400, 404])

Timeout

Global timeout can be set when constructing the client (see :class:`~elasticsearch.Connection`'s timeout parameter) or on a per-request basis using request_timeout (float value in seconds) as part of any API call, this value will get passed to the perform_request method of the connection class:

# only wait for 1 second, regardless of the client's default
es.cluster.health(wait_for_status='yellow', request_timeout=1)

Note

Some API calls also accept a timeout parameter that is passed to Elasticsearch server. This timeout is internal and doesn't guarantee that the request will end in the specified time.

.. py:module:: elasticsearch

Response Filtering

The filter_path parameter is used to reduce the response returned by elasticsearch. For example, to only return _id and _type, do:

es.search(index='test-index', filter_path=['hits.hits._id', 'hits.hits._type'])

It also supports the * wildcard character to match any field or part of a field's name:

es.search(index='test-index', filter_path=['hits.hits._*'])
