module Elasticsearch
  module API
    module Actions
      # Creates or updates a document in an index.
      #
      # @option arguments [String] :id Document ID
      # @option arguments [String] :index The name of the index
      # @option arguments [String] :type The type of the document *Deprecated*
      # @option arguments [String] :wait_for_active_shards Sets the number of shard copies that must be active before proceeding with the index operation. Defaults to 1, meaning the primary shard only. Set to `all` for all shard copies, otherwise set to any non-negative value less than or equal to the total number of copies for the shard (number of replicas + 1)
      # @option arguments [String] :op_type Explicit operation type. Defaults to `index` for requests with an explicit document ID, and to `create`for requests without an explicit document ID (options: index, create)
      # @option arguments [String] :refresh If `true` then refresh the affected shards to make this operation visible to search, if `wait_for` then wait for a refresh to make this operation visible to search, if `false` (the default) then do nothing with refreshes. (options: true, false, wait_for)
      # @option arguments [String] :routing Specific routing value
      # @option arguments [Time] :timeout Explicit operation timeout
      # @option arguments [Number] :version Explicit version number for concurrency control
      # @option arguments [String] :version_type Specific version type (options: internal, external, external_gte)
      # @option arguments [Number] :if_seq_no only perform the index operation if the last operation that has changed the document has the specified sequence number
      # @option arguments [Number] :if_primary_term only perform the index operation if the last operation that has changed the document has the specified primary term
      # @option arguments [String] :pipeline The pipeline id to preprocess incoming documents with
      # @option arguments [Boolean] :require_alias When true, requires destination to be an alias. Default is false
      # @option arguments [Hash] :headers Custom HTTP headers
      # @option arguments [Hash] :body The document (*Required*)
      #
      # *Deprecation notice*:
      # Specifying types in urls has been deprecated
      # Deprecated since version 7.0.0
