Updating a nested document using painless script. The document will be updated only when the condition is met. Trying to get noop response for the failed conditions but not able to get the response in dotNet's NEST bulk update API. How to achieve this ?
Elasticsearch version: 6.2.4,
NEST: 6
Script Query send from dotNet application is given below
Sample code:
```
POST _bulk
{
"update":{
"_index":"test-index",
"_type":"doc",
"_id":456,
"routing":123
}
}{
"script":{
"params":{
"userStatus":"Approved",
"users":{
"uId":6,
"name":"Test"
}
},
"source":" def found = false; for(i in ctx._source.users){ if (i.uId == 6) { i.userStatus = params.userStatus ;}else{ctx.op = 'none'}}"
}
}
```
There is another option where we can throw exception's. Is this the right approach to use ?
```
else{ Debug.explain(ctx._source); ctx.op = 'none'; }}.
```
Please advice.

Please can you edit your question to
- indicate what version of NEST you're using
- indicate what version of Elasticsearch you're targeting
- show the call you're making with NEST
- how you're handling the response, and what you're not able to get on it
With this information, it should be possible to understand what the issue is.

This doesn't include the result parameter to get noop response
public interface IBulkResponseItem
{
//

[JsonPropertyAttribute("\_id")]

//

//

Thanks, I've opened [an issue](https://github.com/elastic/elasticsearch-net/issues/3375) to address for the next release.

Is it a best practice to use ```
`else{ Debug.explain(ctx._source); ctx.op = 'none'; }}.`
To get `404 exception` and handle the noop scenario as an interim solution ?
