Count accuracy is an approximate, but I need actual counts

Elastic Stack Elasticsearch

The total number of unique tags in the system is in fact in the millions because this is a SaaS product. However, users will typically have no more than a couple hundred uniq "accessible" tags. That's why the permissions_cache filter thing is there.

Will this change anything?

here is an example record:

{
  "_index" : "bpd-development",
  "_type" : "contact",
  "_id" : "71",
  "_version" : 2,
  "found" : true,
  "_source" : {
    "contact_id" : 71,
    "id" : 71,
    "company_id" : 2,
    "first_name" : "Aldo",
    "created_at" : "1499925395000",
    "updated_at" : "1500424806000",
    "last_name" : null,
    "first_name_exact" : "aldo",
    "last_name_exact" : "",
    "source_name" : null,
    "lead_source_id" : null,
    "agent_redistribution_status" : "assigned",
    "lender_redistribution_status" : "assigned",
    "last_lender_history_date" : null,
    "last_agent_history_date" : null,
    "last_lender_history_id" : null,
    "last_agent_history_id" : 401,
    "starred_by" : [ ],
    "contact_types_contacts" : [ ],
    "contact_statuses_contacts" : [
      "31"
    ],
    "permissions_cache" : [
      "3",
      "4",
      "6",
      "7",
      "12"
    ],
    "permissions_cache_length" : 5,
    "metadata" : "asdfasdfsadf asdf asfas fsad fsd aldo"
  }
}
