OpenSearch documentation

This site contains the technical documentation for OpenSearch, the Apache 2.0-licensed search, analytics, and visualization suite with advanced security, alerting, SQL support, automated index management, deep performance analysis, and more.

Get started

Why use OpenSearch?

OpenSearch is well-suited to the following use cases:

  • Log analytics
  • Real-time application monitoring
  • Clickstream analytics
  • Search backend
Component Purpose
OpenSearch Data store and search engine
OpenSearch Dashboards Search frontend and visualizations
Security Authentication and access control for your cluster
Alerting Receive notifications when your data meets certain conditions
SQL Use SQL or a piped processing language to query your data
Index State Management Automate index operations
KNN Find “nearest neighbors” in your vector data
Performance Analyzer Monitor and optimize your cluster
Anomaly detection Identify atypical data and receive automatic notifications
Asynchronous search Run search requests in the background
Cross-cluster replication Replicate your data across multiple OpenSearch clusters

Most OpenSearch plugins have corresponding OpenSearch Dashboards plugins that provide a convenient, unified user interface.

For specifics around the project, see the FAQ.

Docker quickstart


  1. Install and start Docker Desktop.
  2. Run the following commands:

    docker pull opensearchproject/opensearch:1.1.0
    docker run -p 9200:9200 -p 9600:9600 -e "discovery.type=single-node" opensearchproject/opensearch:1.1.0
  3. In a new terminal session, run:

    curl -XGET --insecure -u 'admin:admin' 'https://localhost:9200'
  4. Create your first index.

    curl -XPUT --insecure -u 'admin:admin' 'https://localhost:9200/my-first-index'
  5. Add some data to your newly created index.

    curl -XPUT --insecure -u 'admin:admin' 'https://localhost:9200/my-first-index/_doc/1' -H 'Content-Type: application/json' -d '{"Description": "To be or not to be, that is the question."}'
  6. Retrieve the data to see that it was added properly.

    curl -XGET --insecure -u 'admin:admin' 'https://localhost:9200/my-first-index/_doc/1'
  7. After verifying that the data is correct, delete the document.

    curl -XDELETE --insecure -u 'admin:admin' 'https://localhost:9200/my-first-index/_doc/1'
  8. Finally, delete the index.

    curl -XDELETE --insecure -u 'admin:admin' 'https://localhost:9200/my-first-index/'

The secure path forward

OpenSearch includes a demo configuration so that you can get up and running quickly, but before using OpenSearch in a production environment, you must configure the security plugin manually: your own certificates, your own authentication method, your own users, and your own passwords.
