Need help with Terms Aggregation : buckets count

[IanCap (Ian Ducrot)]

Hi everyone !

I'm currently working on a query and want to count the numbers of hits returned.
Given the following query :

GET /index*/_search
{
  "aggs": {
    "ip":   {
      "terms": {
        "field": "ClientIP.ip",
        "min_doc_count": 10000,
        "size": 1000
        }
    }
  }
}

I get the following result :

"aggregations" : {
    "ip" : {
      "doc_count_error_upper_bound" : 363,
      "sum_other_doc_count" : 1888503,
      "buckets" : [
        {
          "key" : "XXX.YYY.ZZZ.AA",
          "doc_count" : 20408
        },
        {
          "key" : "BB.UUU.FFF.AA",
          "doc_count" : 15619
        },
        {
          "key" : "ZZ.EEE.HH.FOO",
          "doc_count" : 12009
        },
        {
...
...
...

I want to get the size of the array "buckets" aka counting the number of hits and have yet to succeed.

Adding a cardinality aggregation the following way doesn't give the wanted result

GET /index*/_search
{
  "aggs": {
    "ip": {
      "terms": {
        "field": "ClientIP.ip",
        "min_doc_count": 10000,
        "size": 1000
      },
      "aggs": {
        "test": {
            "cardinality": {
              "field": "ClientIP.ip"
            }
        }
      }
    }
  }
}

As i get :

"aggregations" : {
    "ip" : {
      "doc_count_error_upper_bound" : 363,
      "sum_other_doc_count" : XXXXXX,
      "buckets" : [
        {
          "key" : "XXX.YYY.ZZZ.AA",
          "doc_count" : 20408,
          "test" : {
            "value" : 1
          }
        },
        {
          "key" : "BB.UUU.FFF.AA",
          "doc_count" : 15619,
          "test" : {
            "value" : 1
          }
        },

I saw on a similar topic some options about _count or buckets_path but i can't use them with a terms aggregation :

I'm looking for a hand here,

Thanks in advance,

Ian
