Get started with the serverless Python client
Set up and use the Python client for serverless Elasticsearch.
This page guides you through the installation process of the Python client for serverless Elasticsearch, shows you how to initialize the client, and how to perform basic Elasticsearch operations with it.
Requirements
- Python 3.7 or higher
pip
Installation
Using the command line
You can install the Python client with the following commands:
python -m pip install elasticsearch-serverless
Initialize the client
Initialize the client using your API key and Elasticsearch Endpoint:
from elasticsearch_serverless import Elasticsearch
client = Elasticsearch(
"https://...", # Your project's Elasticsearch Endpoint
api_key='api-key', # API key for your project
)
To get API keys or the Elasticsearch Endpoint for a project, see Get started.
Using the API
After you've initialized the client, you can start ingesting documents. You can use
the bulk
API for this. This API enables you to index, update, and delete several
documents in one request.
Creating an index and ingesting documents
You can call the bulk
API with a body parameter, an array of hashes that
define the action, and a document.
The following is an example of indexing some classic books into the books
index:
from datetime import datetime
client.bulk(
body=[
{"index": {"_index": "books", "_id": "1"}},
{"title": "Infinite Jest", "author": "David Foster Wallace", "published_on": datetime(1996, 2, 1)},
{"index": {"_index": "books", "_id": "2"}},
{"title": "Ulysses", "author": "James Joyce", "published_on": datetime(1922, 2, 2)},
{"index": {"_index": "books", "_id": "3"}},
{"title": "Just Kids", "author": "Patti Smith", "published_on": datetime(2010, 1, 19)},
],
)
Getting documents
You can get documents by using the following code:
response = client.get(index="books", id="1")
print(response.body)
Searching
Now that some data is available, you can search your documents using the
search
API:
response = client.search(index="books", query={
"match": {
"title": "infinite"
}
})
for hit in response["hits"]["hits"]:
print(hit["_source"])
Updating a document
You can call the update
API to update a document:
client.update(index="books", id="2", doc={
"author": "James Augustine Aloysius Joyce",
"pages": 732,
})
Deleting a document
You can call the delete
API to delete a document:
client.delete(index="books", id="3")
Deleting an index
client.indices.delete(index="books")
