Python Elastic Search driver

Project description

Keywords:search, elastisearch, distribute search

pyes is a connector to use elasticsearch from python.

This version requires elasticsearch 0.12 or above.


  • Thrift/HTTP protocols
  • Bulk insert
  • Index management
  • Every search query types
  • Facet Support
  • Geolocalization support
  • Highlighting
  • Initial River support


These function are taken from pycassa.

Import the module:

>>> import pyes

pyes is able to use standard http or thrift protocol. If your port starts with “92” http protocol is used, otherwise thrift.

For a single connection (which is _not_ thread-safe), pass a list of servers.

For thrift:

>>> client = pyes.connect() # Defaults to connecting to the server at ''
>>> client = pyes.connect([''])

For http:

>>> client = pyes.connect([''])

With thrift protocol, framed transport is the default. You may disable it by passing framed_transport=False.

>>> client = pyes.connect(framed_transport=False)

Thread-local connections opens a connection for every thread that calls an ElasticSearch function. It also automatically balances the number of connections between servers, unless round_robin=False.

>>> client = pyes.connect_thread_local() # Defaults to connecting to the server at ''
>>> client = pyes.connect_thread_local(['', 'other_server:9500']) # Round robin connections
>>> client = pyes.connect_thread_local(['', 'other_server:9500'], round_robin=False) # Connect in list order

With http protocol transport:

>>> client = pyes.connect_thread_local(['', 'other_server:9200']) # Round robin connections
>>> client = pyes.connect_thread_local(['', 'other_server:9200'], round_robin=False) # Connect in list order

Connections are robust to server failures. Upon a disconnection, it will attempt to connect to each server in the list in turn. If no server is available, it will raise a NoServerAvailable exception.

Timeouts are also supported and should be used in production to prevent a thread from freezing while waiting for the server to return.

>>> client = pyes.connect(timeout=3.5) # 3.5 second timeout
(Make some pyes calls and the connection to the server suddenly becomes unresponsive.)

Traceback (most recent call last): … pyes.connection.NoServerAvailable

Note that this only handles socket timeouts.


Creating a connection:

>>> from pyes import *
>>> conn = ES('')

Deleting an index:

>>> try:
>>>     conn.delete_index("test-index")
>>> except:
>>>     pass

(an exception is fored if the index is not present)

Create an index:

>>> conn.create_index("test-index")

Creating a mapping:

>>> mapping = { u'parsedtext': {'boost': 1.0,
>>>                  'index': 'analyzed',
>>>                  'store': 'yes',
>>>                  'type': u'string',
>>>                  "term_vector" : "with_positions_offsets"},
>>>          u'name': {'boost': 1.0,
>>>                     'index': 'analyzed',
>>>                     'store': 'yes',
>>>                     'type': u'string',
>>>                     "term_vector" : "with_positions_offsets"},
>>>          u'title': {'boost': 1.0,
>>>                     'index': 'analyzed',
>>>                     'store': 'yes',
>>>                     'type': u'string',
>>>                     "term_vector" : "with_positions_offsets"},
>>>          u'pos': {'store': 'yes',
>>>                     'type': u'integer'},
>>>          u'uuid': {'boost': 1.0,
>>>                    'index': 'not_analyzed',
>>>                    'store': 'yes',
>>>                    'type': u'string'}}
>>> conn.put_mapping("test-type", {'properties':mapping}, ["test-index"])

Index some documents:

>>> conn.index({"name":"Joe Tester", "parsedtext":"Joe Testere nice guy", "uuid":"11111", "position":1}, "test-index", "test-type", 1)
>>> conn.index({"name":"Bill Baloney", "parsedtext":"Joe Testere nice guy", "uuid":"22222", "position":2}, "test-index", "test-type", 2)

Refresh an index:

>>> conn.refresh(["test-index"])

Execute a query

>>> q = TermQuery("name", "joe")
>>> result = = q)

Note for next release - the order of geolocation parameters expected by elasticsearch changed between ES 0.14.4 and ES 0.15, from [lat, lon] to [lon, lat]. Clients will need to update accordingly, or use an object with named parameters.
