I am trying to get a distinct list of user ids out of ElasticSearch where the user id was in more than one document across about 100M records.

Min\_doc\_count works fine if you are doing normal aggregate counts however if you change the aggregate to a cardinality aggregation, the Min\_doc\_count applies only to the total doc count that make up the aggregate and not the total unique counts within the aggregate.

Has anyone come up with a workaround for this?
