module Elasticsearch
  module API
    module Actions
      # Run a script.
      # Runs a script and returns a result.
      # Use this API to build and test scripts, such as when defining a script for a runtime field.
      # This API requires very few dependencies and is especially useful if you don't have permissions to write documents on a cluster.
      # The API uses several _contexts_, which control how scripts are run, what variables are available at runtime, and what the return type is.
      # Each context requires a script, but additional parameters depend on the context you're using for that script.
      # This functionality is experimental and is not ready for production usage. Experimental
      # features may change or be removed at any time. Elastic will work to fix any issues, but
      # experimental features are not subject to the support SLA of official GA features. Specific
      # Support terms apply.
      #
      # @option arguments [Boolean] :error_trace When set to `true` Elasticsearch will include the full stack trace of errors
      #  when they occur.
      # @option arguments [String, Array<String>] :filter_path Comma-separated list of filters in dot notation which reduce the response
      #  returned by Elasticsearch.
      # @option arguments [Boolean] :human When set to `true` will return statistics in a format suitable for humans.
      #  For example `"exists_time": "1h"` for humans and
      #  `"exists_time_in_millis": 3600000` for computers. When disabled the human
      #  readable values will be omitted. This makes sense for responses being consumed
      #  only by machines.
      # @option arguments [Boolean] :pretty If set to `true` the returned JSON will be "pretty-formatted". Only use
      #  this option for debugging only.
      # @option arguments [Hash] :headers Custom HTTP headers
      # @option arguments [Hash] :body request body
      #
