The REST APIedit
Now that we have our node (and cluster) up and running, the next step is to understand how to communicate with it. Fortunately, Elasticsearch provides a very comprehensive and powerful REST API that you can use to interact with your cluster. Among the few things that can be done with the API are as follows:
- Check your cluster, node, and index health, status, and statistics
- Administer your cluster, node, and index data and metadata
- Perform CRUD (Create, Read, Update, and Delete) and search operations against your indexes
- Execute advanced search operations such as paging, sorting, filtering, scripting, aggregations, and many others
