how to construct higher level domains of a domain in elasticsearch pipeline.  
example:  
input data:

```auto
{
  "domain": "test.main.site.com"
}

```

after extracting we have this:

```auto
{
  "domain": "test.user.site.net",
  "higherLevelDomains": [
    "test.user.site.net",
    "user.site.net",
    "site.net",
    "net"
  ]
}

```

Depending on the use case I'd use [https://www.elastic.co/guide/en/elasticsearch/reference/current/analysis-pathhierarchy-tokenizer.html](https://www.elastic.co/guide/en/elasticsearch/reference/current/analysis-pathhierarchy-tokenizer.html)
