ElasticSearch Blueprints

The score of questions based on the score of each answer

As there are different answers for each question and each query matches against each answer, there should be some mechanism to aggregate the score of each answer to form a final score for the parent, that is, the question:

curl -XPOST 'localhost:9200/posts/post/_search' -d '{
  "query": {
    "has_child": {
      "type": "rating",
      "query": {
        "function_score": {
          "functions": [
            {
              "field_value_factor": {
                "field": "rating"
              }
            }
          ]
        }
      },
      "score_mode": "sum"
    }
  }
}'

And the output is as follows:

{ "took" : 5, "timed_out" : false, "_shards" : { "total" : 5, "successful" : 5, "failed" : 0 }, "hits" : { "total" : 3, "max_score" : 78.0, "hits" : [ { "_index" : "posts", "_type" : "post", "_id" : "1", "_score" : 78.0, ...
