Search by sum of nested objects

[pikorro (dfens)]

I have list of docs with following struct:

{
  "name": "John Doe",
  "work_experiences": [
    {
      "company": "Accenture",
      "duration": 24
    },
    {
      "company": "IBM",
      "duration": 36
    }
  ]
}

curl -X PUT "localhost:9200/testing?pretty" -H 'Content-Type: application/json' -d'
{
  "mappings": {
    "properties": {
      "name": { "type": "text" },
      "work_experiences": {
        "type": "nested",
        "properties": {
          "company": { "type": "text" },
          "duration": { "type": "integer" }
        }
      }
    }
  }
}
'

curl -X POST "localhost:9200/testing/_doc" -H 'Content-Type: application/json' -d '
{
  "name": "John Doe",
  "work_experiences": [
    {
      "company": "Accenture",
      "duration": 24
    },
    {
      "company": "IBM",
      "duration": 36
    }
  ]
}
'


curl -X POST "localhost:9200/testing/_doc" -H 'Content-Type: application/json' -d '
{
  "name": "Jane Smith",
  "work_experiences": [
    {
      "company": "Accenture",
      "duration": 18
    },
    {
      "company": "Google",
      "duration": 42
    },
    {
      "company": "Accenture",
      "duration": 30
    }
  ]
}
'

I want to list all profiles that were working in total at least 40 months in companies with wildcard match *accent* in company name

In mentioned case Jane Smith was working in total 48 monts in accenture. However I have trouble composing query, I was trying script, aggregations etc. On top of that tere are few other conditions but in general question is about filtering by aggregated sum of nested objects
