This node performs a request against Elasticsearch. It gives access to the full REST API of Elasticsearch and allows to execute GET, POST, PUT, and DELETE requests to query and/or modify documents. We recommend using the “JSON to Table” node to convert the JSON result to a table.

Find documentation and examples about the Elasticsearch REST API in the Elasticsearch guide .
