Hi @nishar welcome to the Kibana community. Together with the `doc_count` properties, you can see there's also a `doc_count_error_bound` property set to -1: when this property is not 0 the system detected an count error of some kind - in this case because it is sorted by a sub-aggregation - and it is reporting that detection result. The `terms` aggregation works not in an exact way when multiple shards are involved in order to be fast. To have more info about the `doc_count`, `size` and how errors are reported you can have a look at the official documentation for the `terms` aggregation: [Terms aggregation | Elasticsearch Guide [7.15] | Elastic](https://www.elastic.co/guide/en/elasticsearch/reference/current/search-aggregations-bucket-terms-aggregation.html#_per_bucket_document_count_error) ---

Hi @Marco_Liberati If I increase the size in agg then I'm getting proper result. Is there any way to assign the size dynamically? Please suggest best practice to overcome this issue. ---

Hi friend, Have you tried adding to your \_search, \_search?search\_type=dfs\_quert\_then\_fetch. I don't know if that will fix the issue, but that way you will distributed search your entire cluster and fetch later. It will be slower, but it might fix it. ---
