Hi,

I'm using curator for reindex daily indices into weekly/montly indices and it's work fine.

The current treatment takes all the documents and create the new index, but can curator excludes some documents (filter on a field value) or deletes some fields of a document ?

I managed to reindex with deletion of these specific documents/fields by the \_reindex API, but I 'ld rather use curator to make this action.

Thanks for the answer  
Best regards

François

The answer to this is a resounding [yes](https://www.elastic.co/guide/en/elasticsearch/reference/6.2/docs-reindex.html#docs-reindex). Curator just uses YAML syntax to do anything that you can do with the regular [reindex API](https://www.elastic.co/guide/en/elasticsearch/reference/6.2/docs-reindex.html#docs-reindex).

For example, given this JSON reindex block:

```json
POST _reindex
{
  "source": {
    "index": "twitter",
    "type": "_doc",
    "query": {
      "term": {
        "user": "kimchy"
      }
    }
  },
  "dest": {
    "index": "new_twitter"
  }
}

```

You would create a YAML [`request_body`](https://www.elastic.co/guide/en/elasticsearch/client/curator/5.5/option_request_body.html#_manual_index_selection) like this:

```auto
request_body:
  source:
    index: twitter
    type: _doc
    query:
      term:
        user: kimchy
  dest:
    index: new_twitter

```
