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
TransportError (or a more specific subclass) will be
raised. You can see other exception and error states in 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
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.
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._*'])
