Does es support dot in field name? I have field with name like: "checkbox1.1" and after insert it transforms to object type field(splitted by "."). As i know dots were supported in 2.4 version([https://www.elastic.co/guide/en/elasticsearch/reference/2.4/dots-in-names.html](https://www.elastic.co/guide/en/elasticsearch/reference/2.4/dots-in-names.html)). Is there any option/workaround for fields with dot?

Sure, they are common in ECS, such as beat.name, but in mapping, they appear as nested fields:

```
"beat": {
  "properties": {
    "hostname": {
      "type": "keyword",
      "ignore_above": 1024
    },
    "name": {
      "type": "keyword",
      "ignore_above": 1024
    },
    "timezone": {
      "type": "keyword",
      "ignore_above": 1024
    },
    "version": {
      "type": "keyword",
      "ignore_above": 1024
    }
  }
```
