I'm trying to use reindex with help of ingest pipeline to enrich my data. I have problem with enrich processor.  
I have created this policy

```auto
PUT /_enrich/policy/ingest-policy
{
  "match": {
    "indices": "ingest_two",
    "match_field": "matchingId",
    "enrich_fields": ["textValue"]
  }
}

```

Which is used in this processor:

```auto
    {
      "enrich": {
        "field": "_id",
        "policy_name": "ingest-policy",
        "target_field": "systemMetadata.com:vjoon:System:searchContentHTML",
        "override": true
      }
    }

```

As you can see I'm comparing `_id` with `matchingId` field. It works fine, but `matchingId` is added to the `systemMetadata.com:vjoon:System:searchContentHTML`, which I do not want to do. Can I change this behaviour, co only `textValue` is added and not the `matchingId`?

I don't think this is possible, the `match_field` is always added.

In the documentation there is this description for the `target_field`.

> Field added to incoming documents to contain enrich data. This field contains both the `match_field` and `enrich_fields` specified in the [enrich policy](https://www.elastic.co/guide/en/elasticsearch/reference/current/put-enrich-policy-api.html).

Which seems to indicate that the `match_field` will always be added.

When I used the `enrich processor` a while ago, I had a `remove` processor after it to remove the `match_field` from the enriched documents, I think you will need something in this way.
