Syntax#

curl -X<VERB> ‘<PROTOCOL>://<HOST>:<PORT>/<PATH>?<QUERY_STRING>’ -d ‘<BODY>’
Where:
VERB: The appropriate HTTP method or verb: GET, POST, PUT, HEAD, or DELETE
PROTOCOL: Either http or https (if you have an https proxy in front of Elasticsearch.)
HOST: The hostname of any node in your Elasticsearch cluster, or localhost for a node on your local machine.
PORT: The port running the Elasticsearch HTTP service, which defaults to 9200.
PATH: API Endpoint (for example _count will return the number of documents in the cluster). Path may contain multiple components, such as _cluster/stats or _nodes/stats/jvm
QUERY_STRING: Any optional query-string parameters (for example ?pretty will pretty-print the JSON response to make it easier to read.)
BODY: A JSON-encoded request body (if the request needs one.)
