I have 5000 unique events. If I try to unique count with default precision value, I get the wrong value: ![prec](https://us1.discourse-cdn.com/elastic/original/3X/4/9/495993660e79d743886e98c6a36b24e102beff42.png) How can I calculate truly unique values without changing the precision? ---

Cardinality aggregations and some other types of aggregations [are always approximations](https://www.elastic.co/guide/en/elasticsearch/reference/7.11/search-aggregations-metrics-cardinality-aggregation.html#_counts_are_approximate). Even though you can tune the threshold they are never going to be guaranteed to be exact. ---
