How exclude fields from _source with spring data elasticsearch?

The @Query annotation contains no options for this.
I can’t add –

{
  "_source": {
    "includes": [
      "id",
      "name",
      "address"
    ]
  },
  "query": {
    ...
  }
}

Projections don’t work in ES repositories.

The only way is to make your own repository (NativeSearchQuery and ect.) or DTO?
Why can’t these things be made easier?

>Solution :

All the query implementations from Spring Data Elasticsearch have the possibility to set a source filter.

The @Query annotation can only contain the query part as you wrote, there is already a ticket to make this more flexible.

Well, Spring Data Elasticsearch is a community driven project, so if you want to contribute to it, you are welcome.
