Endpoint

Introduced 1.0 {: .label .label-purple }

To send a query request to PPL plugin, use the HTTP POST request. We recommend a POST request because it doesn't have any length limit and it allows you to pass other parameters to the plugin for other functionality.

Use the _explain endpoint for query translation and troubleshooting.

Request Format

To use the PPL plugin with your own applications, send requests to _plugins/_ppl, with your query in the request body:

curl -H 'Content-Type: application/json' -X POST localhost:9200/_plugins/_ppl \
... -d '{"query" : "source=accounts | fields firstname, lastname"}'
