Quick start guide
editQuick start guide
editThis guide helps you learn how to:
- Run Elasticsearch and Kibana (using Elastic Cloud or in a local Docker dev environment),
- add simple (non-timestamped) dataset to Elasticsearch,
- run basic searches.
If you’re interested in using Elasticsearch with Python, check out Elastic Search Labs. This is the best place to explore AI-powered search use cases, such as working with embeddings, vector search, and retrieval augmented generation (RAG).
- Tutorial: this walks you through building a complete search solution with Elasticsearch, from the ground up.
-
elasticsearch-labs
repository: it contains a range of Python notebooks and example apps.
Run Elasticsearch
editThe simplest way to set up Elasticsearch is to create a managed deployment with Elasticsearch Service on Elastic Cloud. If you prefer to manage your own test environment, install and run Elasticsearch using Docker.
- Sign up for a free trial.
- Follow the on-screen steps to create your first project.
- Click Continue to open Kibana, the user interface for Elastic Cloud.
- Click Explore on my own.
Refer to our quickstart local dev instructions to quickly spin up a local development environment in Docker. If you don’t need Kibana, you’ll only need one docker run
command to start Elasticsearch. Please note that this setup is not suitable for production use.
Send requests to Elasticsearch
editYou send data and other requests to Elasticsearch using REST APIs. This lets you interact with Elasticsearch using any client that sends HTTP requests, such as curl. You can also use Kibana’s Console to send requests to Elasticsearch.
Use Kibana
-
Open Kibana’s main menu ("☰" near Elastic logo) and go to Dev Tools > Console.
-
Run the following test API request in Console:
$response = $client->info();
response = client.info puts response
res, err := es.Info() fmt.Println(res, err)
const response = await client.info() console.log(response)
GET /
Use curl
To communicate with Elasticsearch using curl or another client, you need your cluster’s endpoint.
- Open Kibana’s main menu and click Manage this deployment.
- From your deployment menu, go to the Elasticsearch page. Click Copy endpoint.
-
To submit an example API request, run the following curl command in a new terminal session. Replace
<password>
with the password for theelastic
user. Replace<elasticsearch_endpoint>
with your endpoint.curl -u elastic:<password> <elasticsearch_endpoint>/
Use Kibana
-
Open Kibana’s main menu ("☰" near Elastic logo) and go to Dev Tools > Console.
-
Run the following test API request in Console:
$response = $client->info();
response = client.info puts response
res, err := es.Info() fmt.Println(res, err)
const response = await client.info() console.log(response)
GET /
Use curl
To submit an example API request, run the following curl command in a new terminal session.
curl -u elastic:$ELASTIC_PASSWORD https://localhost:9200
Add data
editYou add data to Elasticsearch as JSON objects called documents. Elasticsearch stores these documents in searchable indices.
Add a single document
editSubmit the following indexing request to add a single document to the
books
index.
The request automatically creates the index.
response = client.index( index: 'books', body: { name: 'Snow Crash', author: 'Neal Stephenson', release_date: '1992-06-01', page_count: 470 } ) puts response
const response = await client.index({ index: 'books', document: { name: 'Snow Crash', author: 'Neal Stephenson', release_date: '1992-06-01', page_count: 470, } }) console.log(response)
POST books/_doc {"name": "Snow Crash", "author": "Neal Stephenson", "release_date": "1992-06-01", "page_count": 470}
The response includes metadata that Elasticsearch generates for the document including a unique _id
for the document within the index.
Expand to see example response
Add multiple documents
editUse the _bulk
endpoint to add multiple documents in one request. Bulk data
must be newline-delimited JSON (NDJSON). Each line must end in a newline
character (\n
), including the last line.
response = client.bulk( body: [ { index: { _index: 'books' } }, { name: 'Revelation Space', author: 'Alastair Reynolds', release_date: '2000-03-15', page_count: 585 }, { index: { _index: 'books' } }, { name: '1984', author: 'George Orwell', release_date: '1985-06-01', page_count: 328 }, { index: { _index: 'books' } }, { name: 'Fahrenheit 451', author: 'Ray Bradbury', release_date: '1953-10-15', page_count: 227 }, { index: { _index: 'books' } }, { name: 'Brave New World', author: 'Aldous Huxley', release_date: '1932-06-01', page_count: 268 }, { index: { _index: 'books' } }, { name: 'The Handmaids Tale', author: 'Margaret Atwood', release_date: '1985-06-01', page_count: 311 } ] ) puts response
const response = await client.bulk({ operations: [ { index: { _index: 'books' } }, { name: 'Revelation Space', author: 'Alastair Reynolds', release_date: '2000-03-15', page_count: 585, }, { index: { _index: 'books' } }, { name: '1984', author: 'George Orwell', release_date: '1985-06-01', page_count: 328, }, { index: { _index: 'books' } }, { name: 'Fahrenheit 451', author: 'Ray Bradbury', release_date: '1953-10-15', page_count: 227, }, { index: { _index: 'books' } }, { name: 'Brave New World', author: 'Aldous Huxley', release_date: '1932-06-01', page_count: 268, }, { index: { _index: 'books' } }, { name: 'The Handmaids Tale', author: 'Margaret Atwood', release_date: '1985-06-01', page_count: 311, } ] }) console.log(response)
POST /_bulk { "index" : { "_index" : "books" } } {"name": "Revelation Space", "author": "Alastair Reynolds", "release_date": "2000-03-15", "page_count": 585} { "index" : { "_index" : "books" } } {"name": "1984", "author": "George Orwell", "release_date": "1985-06-01", "page_count": 328} { "index" : { "_index" : "books" } } {"name": "Fahrenheit 451", "author": "Ray Bradbury", "release_date": "1953-10-15", "page_count": 227} { "index" : { "_index" : "books" } } {"name": "Brave New World", "author": "Aldous Huxley", "release_date": "1932-06-01", "page_count": 268} { "index" : { "_index" : "books" } } {"name": "The Handmaids Tale", "author": "Margaret Atwood", "release_date": "1985-06-01", "page_count": 311}
You should receive a response indicating there were no errors.

Search data
editIndexed documents are available for search in near real-time.
Search all documents
editRun the following command to search the books
index for all documents:
response = client.search( index: 'books' ) puts response
const response = await client.search({ index: 'books' }) console.log(response)
GET books/_search
The _source
of each hit contains the original
JSON object submitted during indexing.
match
query
editYou can use the match
query to search for documents that contain a specific value in a specific field.
This is the standard query for performing full-text search, including fuzzy matching and phrase searches.
Run the following command to search the books
index for documents containing brave
in the name
field:
response = client.search( index: 'books', body: { query: { match: { name: 'brave' } } } ) puts response
const response = await client.search({ index: 'books', query: { match: { name: 'brave' } } }) console.log(response)
GET books/_search { "query": { "match": { "name": "brave" } } }
Next steps
editNow that Elasticsearch is up and running and you’ve learned the basics, you’ll probably want to test out larger datasets, or index your own data.
