I am using cardinality aggregation which is giving me wrong values when I am not specifying any value for precision threshol but when specifying any value greater than cardinality result it is givng me the correct value. I suppose default value is 100 but on giving explicitly less than 100 also is giving me correct result but incorrect for default value. Can anyone tell me what it uses as precision threshol when no value is specified?

The default value is 3000, see - [https://www.elastic.co/guide/en/elasticsearch/reference/5.4/search-aggregations-metrics-cardinality-aggregation.html#\_precision\_control](https://www.elastic.co/guide/en/elasticsearch/reference/5.4/search-aggregations-metrics-cardinality-aggregation.html#_precision_control)
