Change multiple fields with different variable

Hi,
I am using version -> elasticsearch-7.5.2
I want to change multiple fields for a specific index.
each field should get a different value.
I am using c#
Is it possible?

currently, it changes all the fields for the same variable.

This is my code:
UpdateByQueryResponse task = ElasticClient.UpdateByQuery(u => u.Index("test")
.Query(q => q
.MatchAll()
).Script(d => d
.Source("ctx._source.wcf += 1;").Lang("painless"));

Thanks.

Your question

Is that something you want to do constantly? What is the use case for this?
Do you have a JSON example of a document you'd like to modify? And a typical JSON document of what it should look like at the end?

Hi,
Thanks for the fast response.

Is that something you want to do constantly?
-This is something I'd like to do under specific circumstances when I need to number my documents in a specific manner.

What is the use case for this?
-Numbering documents according to this field.

Do you have a JSON example of a document you'd like to modify? And a typical JSON document of what it should look like at the end?

Before:

    {
    "_index": "test",
    "_type": "_doc",
    "_id": "aaaa",
    "_version": 1,
    "_score": 1,
    "_source": {
    "wcf": ""
    }

{
"_index": "test",
"_type": "_doc",
"_id": "bbbb",
"_version": 1,
"_score": 1,
"_source": {
"wcf": ""
}

 

After we run the updateByQuery (note the WCF field has changed):

{
"_index": "test",
"_type": "_doc",
"_id": "aaaa",
"_version": 1,
"_score": 1,
"_source": {
"wcf": "1"
}


{
"_index": "test",
"_type": "_doc",
"_id": "bbbb",
"_version": 1,
"_score": 1,
"_source": {
"wcf": "2"
}

Currently, I am able to change the WCF field but for the same value to all the documents.

Thanks.

I think you did not read the "Code formatting" part of my answer. Please update your post.
Also in your examples please remove all non needed fields. That will help to focus on the actual problem.
