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.
