With this documentation, you’ll learn how to use OpenSearch — the only 100% open-source search, analytics, and visualization suite. We have a dedicated and growing number of technical writers who are building our documentation library. We also welcome and encourage community input. To contribute, see the [Contributing](https://opensearch.org/source.html) file. A good place to start is by browsing issues labeled “_good first issue_.” ## Getting started - [About OpenSearch]({{site.url}}{{site.baseurl}}/opensearch/) - [Install OpenSearch]({{site.url}}{{site.baseurl}}/opensearch/install/) - [Install OpenSearch Dashboards]({{site.url}}{{site.baseurl}}/dashboards/install/) - [See the FAQ](https://opensearch.org/faq) ## Why use OpenSearch? With OpenSearch, you can perform the following use cases: ![](images/1_search.png) | ![](images/2_monitoring.png)|![](images/3_security.png) | ![](images/4_tracking.png) :--- | :--- | :--- | :--- | **Fast, Scalable Full-text Search** | **Application and Infrastructure Monitoring** | **Security and Event Information Management** | **Operational Health Tracking** Help users find the right information within your application, website, or data lake catalog. | Easily store and analyze log data, and set automated alerts for underperformance. | Centralize logs to enable real-time security monitoring and forensic analysis. | Use observability logs, metrics, and traces to monitor your applications and business in real time. **Additional features and plugins:** OpenSearch has several features and plugins to help index, secure, monitor, and analyze your data. Most OpenSearch plugins have corresponding OpenSearch Dashboards plugins that provide a convenient, unified user interface. - [Anomaly detection]({{site.url}}{{site.baseurl}}/monitoring-plugins/ad/) - Identify atypical data and receive automatic notifications - [KNN]({{site.url}}{{site.baseurl}}/search-plugins/knn/) - Find “nearest neighbors” in your vector data - [Performance Analyzer]({{site.url}}{{site.baseurl}}/monitoring-plugins/pa/) - Monitor and optimize your cluster - [SQL]({{site.url}}{{site.baseurl}}/search-plugins/sql/) - Use SQL or a piped processing language to query your data - [Index State Management]({{site.url}}{{site.baseurl}}/im-plugin/) - Automate index operations - [ML Commons plugin]({{site.url}}{{site.baseurl}}/ml-commons-plugin/index/) - Train and execute machine-learning models - [Asynchronous search]({{site.url}}{{site.baseurl}}/search-plugins/async/) - Run search requests in the background - [Cross-cluster replication]({{site.url}}{{site.baseurl}}/replication-plugin/index/) - Replicate your data across multiple OpenSearch clusters ## Docker quickstart Docker {: .label .label-green } The best way to try out OpenSearch is to use Docker Compose. Setting up OpenSearch with Docker Compose sets up a two-node cluster of OpenSearch plus OpenSearch Dashboards. 1. Install and start [Docker Desktop](https://www.docker.com/products/docker-desktop). 1. Run the following commands: ```bash docker pull opensearchproject/opensearch:{{site.opensearch_version}} docker run -p 9200:9200 -p 9600:9600 -e "discovery.type=single-node" opensearchproject/opensearch:{{site.opensearch_version}} ``` 1. In a new terminal session, run: ```bash curl -XGET --insecure -u 'admin:admin' 'https://localhost:9200' ``` 1. [Create]({{site.url}}{{site.baseurl}}/opensearch/rest-api/index-apis/create-index/) your first index. ```bash curl -XPUT --insecure -u 'admin:admin' 'https://localhost:9200/my-first-index' ``` 1. [Add some data]({{site.url}}{{site.baseurl}}/opensearch/index-data/) to your newly created index. ```bash 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."}' ``` 1. [Retrieve the data]({{site.url}}{{site.baseurl}}/opensearch/index-data/#read-data) to see that it was added properly. ```bash curl -XGET --insecure -u 'admin:admin' 'https://localhost:9200/my-first-index/_doc/1' ``` 1. After verifying that the data is correct, [delete the document]({{site.url}}{{site.baseurl}}/opensearch/index-data/#delete-data). ```bash curl -XDELETE --insecure -u 'admin:admin' 'https://localhost:9200/my-first-index/_doc/1' ``` 1. Finally, [delete the index]({{site.url}}{{site.baseurl}}/opensearch/rest-api/index-apis/delete-index). ```bash curl -XDELETE --insecure -u 'admin:admin' 'https://localhost:9200/my-first-index/' ``` To learn more, see [Docker image]({{site.url}}{{site.baseurl}}/opensearch/install/docker/) and [Docker security configuration]({{site.url}}{{site.baseurl}}/opensearch/install/docker-security/). ## 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]({{site.url}}{{site.baseurl}}/security-plugin/configuration/index/) with your own certificates, authentication method, users, and passwords. ## Looking for the Javadoc?
