Alternative 2:

GET /test_sum_bucket_agg/_search
{
  "runtime_mappings": {
    "countAC": {
      "type": "long",
      "script":{
        "lang": "painless",
        "source": "int x=0; for (sename in doc['currentApplicantInfo.seName']){if ((sename == 'ALLOGENE THERAPEUTICS') || (sename == 'CELLECTIS')){x = x+1}} emit(x)"
      }
    }
  },
  "size":0,
  "fields": [
    {"field": "countAC"}
  ],
  "aggs":{
    "STUB":{
      "sum":{
        "field": "countAC",
        "format": "#"
      }
    },
    "terms":{
      "terms":{
        "field":"currentApplicantInfo.seName"
      }
    }
  }
}

{
  "took" : 2,
  "timed_out" : false,
  "_shards" : {
    "total" : 1,
    "successful" : 1,
    "skipped" : 0,
    "failed" : 0
  },
  "hits" : {
    "total" : {
      "value" : 3,
      "relation" : "eq"
    },
    "max_score" : null,
    "hits" : [ ]
  },
  "aggregations" : {
    "terms" : {
      "doc_count_error_upper_bound" : 0,
      "sum_other_doc_count" : 0,
      "buckets" : [
        {
          "key" : "ALLOGENE THERAPEUTICS",
          "doc_count" : 3
        },
        {
          "key" : "CELLECTIS",
          "doc_count" : 1
        },
        {
          "key" : "PFIZER",
          "doc_count" : 1
        }
      ]
    },
    "STUB" : {
      "value" : 4.0,
      "value_as_string" : "4"
    }
  }
}

I also recommend to do it on the client side as he said on another topic.
