API conventions

edit

The Elasticsearch REST APIs are exposed over HTTP.

A number of Elasticsearch GET APIs—​most notably the search API—​support a request body. While the GET action makes sense in the context of retrieving information, GET requests with a body are not supported by all HTTP libraries. All Elasticsearch GET APIs that require a body can also be submitted as POST requests. Alternatively, you can pass the request body as the source query string parameter when using GET.
