Hi! I'd like to know a simple thing: in a visualization (e.g. Table visualization), using a Count aggregation, I can filter the results by writing {"min\_doc\_count":2} in the JSON input field. Unfortunately, the same syntax will not work if the aggregation is a Unique Count. Is there an equivalent way to accomplish such a task? Thank you! ---

As far as I can tell, this is currently not supported. Underneath the hood, unique count is doing a cardinality aggregation, and I don't see an option for filtering: [https://www.elastic.co/guide/en/elasticsearch/reference/current/search-aggregations-metrics-cardinality-aggregation.html](https://www.elastic.co/guide/en/elasticsearch/reference/current/search-aggregations-metrics-cardinality-aggregation.html) ---
