Total doc_count aggregations

[Miguel_BA (Miguel Barrios)]

I am looking for a way to sum up the Total doc_count aggregations that I have defined in the query. I will try to explain my question through the following simple representative example:

 {
      "name" : false,
      "surname" : false
    
  },
  {
      "name" : false,
      "surname" : false
  }

Query:

GET index/_search?size=0
{"query": {
  "bool": {
    "must": [
      {"term": {"name": false}},
      {"term": {"surname": false}}
    ]
  }
},
  "aggs": {
    "name": {
      "terms": {
        "field": "name"
      }
    },
    "surname": {
      "terms": {
        "field": "surname"
      }
    }
  }
}

The query returns the value for each field " name " and " surname " with value "false".

  "aggregations" : {
    "name" : {
      "doc_count_error_upper_bound" : 0,
      "sum_other_doc_count" : 0,
      "buckets" : [
        {
          "key" : 0,
          "key_as_string" : "false",
          "doc_count" : 2 <---------
        }
      ]
    },
    "surname" : {
      "doc_count_error_upper_bound" : 0,
      "sum_other_doc_count" : 0,
      "buckets" : [
        {
          "key" : 0,
          "key_as_string" : "false",
          "doc_count" : 2 <---------
        }
      ]
    }
  }
}

Is it possible to return the total sum of doc_count, so that in this situation it would be "doc_count" : 2 + "doc_count" : 2 == 4 ?
If I get the total doc_count, it would reduce a lot of GET in the process of querying the data.
I've been trying to do it with script but since they are boolean values it doesn't work.

Hi,

You may obtain the value by using Sum Bucket Aggregation.

But with the shared query, I suppose documents with 'name' == false AND 'surname' ==false will match and doc_count in 'name' aggregation and doc_count in 'surname' aggregation must be the same. Is it your intent?
If you want to query OR, you may use "should" clause and "minimum_should_match" parameter in Boolean query.
