I am using Nest 7.9 client to bulk update documents in a huge index. Followed below 6.6 link to set up updates in C#

> I am really surprised by the lack of documentation for the NEST client. I am using NEST 6.6.0. I have an array of partial documents (anonymous objects) -- each includes an id field and the fields that I want to update. Please show me an example of how to do this. I've seen an example where the you have to pass an IEnumerable\< T \> instead of IEnumerable\< TPartial \>, but that doesn't make sense. I have a bunch of partial documents that include the ids already. Is there a way to do this?
```auto
List jiras = new List();
JObject id1 = new JObject();
id1.Add("id", "vlHNQnEBb8EcauKoEC0r");id1.Add("_type", "_doc");id1.Add("issue", "VIPENG - 37376");
JObject id2 = new JObject();
id2.Add("id", "lHFQnEBb8EcauKowyzQ");
id2.Add("_type", "_doc");
jiras.Add(id1); jiras.Add(id2);
var bulkResponse = client.Bulk(b => b
.Index("issue_updated")
.UpdateMany(jiras.ToArray(), (bu, d) => bu.Doc(d)));
```
Not able to set id,type for documents as shown below
```auto
# Invalid Bulk items:
# Audit trail of this API call:
- [1] BadResponse: Node: https://elasticscm-dev.com/ Took: 00:00:01.1550475
# OriginalException: Elasticsearch.Net.ElasticsearchClientException: Request failed to execute. Call: Status code 400 from: POST /issue_updated/_bulk. ServerError: Type: action_request_validation_exception Reason: "Validation Failed: 1: type is missing;2: id is missing;3: type is missing;4: id is missing;"
# Request:
{"update":{"_id":null}}
{"doc":{"id":"vlHNQnEBb8EcauKoEC0r","_type":"_doc","issue":"VIPENG - 37376"}}
{"update":{"_id":null}}
{"doc":{"id":"lHFQnEBb8EcauKowyzQ","_type":"_doc"}}
```
Can someone please let me know how to set id and type of bulk documents?

Assuming you're also using `JsonNetSerializer`, the `.Id()` should also be set in the `UpdateMany()` call, since NEST has no way of inferring an Id property from an instance of `JObject`
```auto
List jiras = new List();
JObject id1 = new JObject();
id1.Add("id", "vlHNQnEBb8EcauKoEC0r"); id1.Add("_type", "_doc"); id1.Add("issue", "VIPENG - 37376");
JObject id2 = new JObject();
id2.Add("id", "lHFQnEBb8EcauKowyzQ");
id2.Add("_type", "_doc");
jiras.Add(id1); jiras.Add(id2);
var bulkResponse = client.Bulk(b => b
.Index("issue_updated")
.UpdateMany(jiras, (bu, d) => bu.Doc(d).Id(d["id"].Value()))
);
```
NEST 7.9 does not expose setting a document type, and `"_doc"` is the value automatically used by Elasticsearch 7.x, so no need to set it.
