Hi ,

I am using elasticsearch 5.4.2 and kibana also 5.4.2 . I want to check distinct counts for a string value field in elasticsearch .  
Unique count greater than Count

Count

In order to perform well at scale [the cardinality aggregation is an approximation](https://www.elastic.co/guide/en/elasticsearch/reference/6.5/search-aggregations-metrics-cardinality-aggregation.html#_counts_are_approximate), although you can tune this to some extent. The reason behind this is described well in [this post](https://discuss.elastic.co/t/background-count-in-significant-terms-not-consistent/55824/8).
