elasticsearchHow do I use Elasticsearch with Python?

Using Elasticsearch with Python is easy and straightforward. The elasticsearch-py client library can be used to interface with an Elasticsearch cluster. The library provides a convenient Python API to access the cluster's indices and documents.

To get started, install the elasticsearch package using pip:

pip install elasticsearch

Once the package is installed, you can use it to connect to an Elasticsearch cluster:

from elasticsearch import Elasticsearch

es = Elasticsearch([{'host': 'localhost', 'port': 9200}])

Once the connection is established, you can use the es object to interact with the cluster. For example, to list all indices in the cluster:

es.indices.get_alias("*")

The output of the above command could look like this:

{
    'index-1': {},
    'index-2': {},
    'index-3': {}
}

You can also use the es object to create, update and delete documents in the cluster's indices. For example, to index a document:

doc = {
    'name': 'John Doe',
    'age': 33
}

es.index(index='users', doc_type='_doc', id=1, body=doc)

You can find more information about using elasticsearch-py in the official documentation.
