Goal

For each value from a terms aggregation, get the count of documents that abide to the condition of lte to that value.

My query:

{
  ...
  "aggs": {
    "all_values": {
      "terms": {
        "field": "characteristics.values.value" //for each of these values
      }
    }
  },
  "nested": {
    "path": "characteristics.values"
  }
}

Note: The characteristics.values.value is a keyword, so I will somehow have to use a script or some other approach to convert it to numeric/interger. I cannot change it from keyword as the code generating the query is generic for other queries as well.

With scipt, it should be something like this?:

"source": "Float.parseFloat(doc['characteristics.values.value'].value).value"
