Hi,

I have events which contains a numeric field action.id.  
When I filter **action.id to be present** for these events and aggregate for **count** and **unique count** I get different values.

I understand it this way, that one or some action.ids have a count of more than one.  
Currently I am talking about 100,000 messages.

I need to retrieve all events, where the action.id occurs in more than one event.  
How do I do this?

Can I do it in kibana?

You should be able to do so with `count` but you may have to set the JSON input to `{ “min_doc_count”: 2 }` in order to show values higher than 1. See example here [Retrieve duplicate data using Kibana search bar](https://discuss.elastic.co/t/retrieve-duplicate-data-using-kibana-search-bar/74229/2).
