I can not just copy and paste your script to run it in Kibana dev console. As we wrote in the [About the Elasticsearch category](https://discuss.elastic.co/t/about-the-elasticsearch-category/21) guide, could you provide something like:

```auto
DELETE index
PUT index/_doc/1
{
  "foo": "bar"
}
GET index/_search
{
  "query": {
    "match": {
      "foo": "bar"
    }
  }
}

```
