Connections to ElasticSearch

The djangoes package provides a simple way to use and to access the default connection to your ElasticSearch server. In any of your python file of your Django project, simply import connection like this:

from djangoes import connection

Then in any function or method you need to perform a query, you can use the methods from the ElasticSearch python library by using this connection object:

def search_blog_entries(words):
    """Search for all blog entries with ``words`` found in entry body."""
    doc_type = 'entry'
    search = {
        'query': {
            'term': {
                'text': words
    result =, search)

    # Result from ES "as is", not modified by djangoes.
    return result.get('hits', {}).get('hits', [])

If you want to select a specific connection, you can import connections instead:

from djangoes import connections

And it can be used like this:

# in some function or method
conn = connections['connection_alias']

In fact, the connection object is a simple proxy to the default connection, simply named default:

>>> from djangoes import connection, connections
>>> connection == connections['default']

Threading and multiprocessing

Using connection or connections is thread-safe, but you should never use a connection object itself in multiple threads. If you need to “share” a connection from one thread to another, simply use its alias and get it using connections[alias] into the threaded code.

The same way, you shoulw never share a connection object between multiple process (either with multiprocessing or forking), and instead use the connection shortcut or connections[alias] to get any connection.

Connection’s methods are not thread or multi-process safe by themselves, and an unappropriate usage may end in unexpected behavior.
