Hello, im new in ELK and dont know how to find only the documents where the value of serviceName It is not repeated, just show me the document with the serviceName SLA\_D\_CARGA\_MODELO\_ACTIVO\_SSII\_testemail with the devtools in kibana. I do not want to find it by looking for it by name, but because it does not repeat itself. Sorry for my language, im not very good in english.

Trying running a [rare-terms aggregation](https://www.elastic.co/guide/en/elasticsearch/reference/current/search-aggregations-bucket-rare-terms-aggregation.html) in console.

Below is an example from the documenation.

```auto
GET /_search
{
  "aggs": {
    "genres": {
      "rare_terms": {
        "field": "genre",
        "max_doc_count": 1
      }
    }
  }
}

```
