In Elasticsearch's nested data type, the "not\_analyzed" attribute indicates that the field should be indexed but not analyzed, meaning that the field's value will be stored as is, without any tokenization or analysis. This is useful for fields that you want to search and filter on, but don't want Elasticsearch to modify the field's value in any way. ---

Hi @reza_setareh, Which version of the client where you using before? By `not_analyzed` are you referring to the old strong `analyzed` and `not_analyzed` behaviour as referenced in this [old topic](https://discuss.elastic.co/t/index-not-analyzed/126606) and [blog post](https://www.elastic.co/blog/strings-are-dead-long-live-strings)? If so I think you're looking to make use of the `keyword` type that replaced `not_analyzed`. If you're using the [automapping feature of the client](https://www.elastic.co/guide/en/elasticsearch/client/net-api/7.17/auto-map.html#auto-map) it should infer the type to give text with a keyword subfield for String, or keyword for a couple of other types as per the [documentation](https://www.elastic.co/guide/en/elasticsearch/client/net-api/7.17/auto-map.html#inferred-dotnet-type-mapping). Or alternatively you can map manually [similar to the example in the documentation](https://www.elastic.co/guide/en/elasticsearch/client/net-api/7.17/fluent-mapping.html#_manual_mapping). Do let me know if that is what you're not trying to do. Hope that helps! ---

That is what keyword is intended for. There's more details in the [documentation](https://www.elastic.co/guide/en/elasticsearch/reference/current/keyword.html) if that helps. ---
