-** *`refresh` (Optional, Enum(true | false | "wait_for"))*: 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.
-** *`routing` (Optional, string)*: Specific routing value
-** *`_source` (Optional, boolean | string | string[])*: True or false to return the _source field or not, or default list of fields to return, can be overridden on each sub-request

-** *`_source_includes` (Optional, string | string[])*: Default list of fields to extract and return from the _source field, can be overridden on each sub-request
-** *`timeout` (Optional, string | -1 | 0)*: Explicit operation timeout
-** *`wait_for_active_shards` (Optional, number | Enum("all" | "index-setting"))*: Sets the number of shard copies that must be active before proceeding with the bulk 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)
-** *`require_alias` (Optional, boolean)*: Sets require_alias for all incoming documents. Defaults to unset (false)
+** *`pipeline` (Optional, string)*: ID of the pipeline to use to preprocess incoming documents.
+If the index has a default ingest pipeline specified, then setting the value to `_none` disables the default ingest pipeline for this request.
+If a final pipeline is configured it will always run, regardless of the value of this parameter.
+** *`refresh` (Optional, Enum(true | false | "wait_for"))*: If `true`, Elasticsearch refreshes 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` do nothing with refreshes.
+Valid values: `true`, `false`, `wait_for`.
+** *`routing` (Optional, string)*: Custom value used to route operations to a specific shard.
+** *`_source` (Optional, boolean | string | string[])*: `true` or `false` to return the `_source` field or not, or a list of fields to return.
+** *`_source_excludes` (Optional, string | string[])*: A list of source fields to exclude from the response.
+** *`_source_includes` (Optional, string | string[])*: A list of source fields to include in the response.
+** *`timeout` (Optional, string | -1 | 0)*: Period each action waits for the following operations: automatic index creation, dynamic mapping updates, waiting for active shards.
+** *`wait_for_active_shards` (Optional, number | Enum("all" | "index-setting"))*: The number of shard copies that must be active before proceeding with the operation.
+Set to all or any positive integer up to the total number of shards in the index (`number_of_replicas+1`).
+** *`require_alias` (Optional, boolean)*: If `true`, the request’s actions must target an index alias.
