Hi All

I have a JSON structure but the fields could be changing. I went through this article to convert JSON into a string and make it searchable. Is there a way to set the mapping as JSON and still searchable without causing [mapping explosion](https://www.elastic.co/blog/found-crash-elasticsearch#mapping-explosion)

[https://discuss.elastic.co/t/unmapped-searchable-json-field/6402/8](https://discuss.elastic.co/t/unmapped-searchable-json-field/6402/8)

For example, incoming data for the first time could be

```auto
    {
    "log":{
             "team":"demo",
             "manager":"test"
    }

```

Next time the data could come as

```auto
  {
    "log":{
             "team":"demo",
             "manager":"test",
             "data":"check"
    }
}

```

No, that's the tradeoff you need to make with Elasticsearch at the moment.
