Hello Guys, I have 100,000 records in an index. I am using a filter which reduces the record count to 2077, When I use aggregation on field along with filter( 2077 records) the result deviates.( Expected : 6 , Actual : 4 ).

Query:

```auto
"aggs": {
    "person_name": {
      "terms": {
        "field": "name.keyword",
        "size": 5,
        "show_term_doc_count_error": true
      }
    }
  }

```

The response shows "doc\_count\_error\_upper\_bound": 9 , Why it so high for such small records and in single instance ( not cluster ). And is there any work around?.  
Please provide some suggestions.  
Thanks,

---

We have a good explanation of this [here](https://www.elastic.co/guide/en/elasticsearch/reference/current/search-aggregations-bucket-terms-aggregation.html#_per_bucket_document_count_error). Basically, it's an upper bound that's is calculated based on what is returned by each shard.
