I have an Elasticsearch cluster, which contains an index called `persons`. I want to query and sort the documents of the index using the latest Elasticsearch client for .NET (Elastic.Clients.Elasticsearch 8.1.0 .NET). The query I want to execute should like this (note: `persons` index contains documents with a `name` field):

```auto
GET persons/_search
{
  "query": {
    "match_all": {}
  },
  "sort": [
    {
      "name.keyword": {
        "order": "asc"
      }
    }
  ]
}

```

Currently I am using this code to execute the above shown query via C#:

```auto
var response = await _elasticsearchClient.SearchAsync<Person>(s => s
    .Index("persons")
    .Query(q => q.MatchAll())
    .Sort(so => so
        .Field(f => f.Name.Suffix("keyword"))
        .Score(sc => sc.Order(SortOrder.Asc))));

```

Unfortunately, this query does not actually sort the documents. Therefore, I want to ask how I could represent the above mentioned query using the 8.1.0 .NET client. The way it used to work in the client with version 7.17 does not work anymore ([Sort Usage 7.17](https://www.elastic.co/guide/en/elasticsearch/client/net-api/7.17/sort-usage.html)).

Hi, @felix-stnr.

Your code is close but is actually setting a score sort. To achieve your goal, you need to provide the `FieldSort` after providing the field name.

```auto
var response = await client.SearchAsync<Person>(s => s
	.Index("persons")
	.Query(q => q.MatchAll())
	.Sort(so => so
		.Field(f => f.Name.Suffix("keyword"), new FieldSort { Order = SortOrder.Asc })));

```

Thanks, that did the trick for me!
