Min_score for a "must" in a bool query in Elasticsearch

Question

Is there a way to apply a minimum score to a must clause in a bool query in elasticsearch.

I want to be able to do something like this:

{
  "query": {
     "bool": {
        "must": [
            {
              "match": {
                 "name": {
                    "query":"A Name",
                    "min_score": 0.3
                 }
               }
            },
            {
              "match": {
                 "address": {
                    "query":"1 Somewhere Street, Somewhereset, UK",
                    "min_score": 0.3
                 }
               }
            }
        ]
    }
  }
}

Which would require the name query to match with a score > 0.3 and the address query to match with a score > 0.3 for the document to be returned. This is to stop really good name matches being returned despite having a terrible address match (e.g. just matching the 1) and vice versa.

I'm currently using Elasticsearch 1.5, but I've also wanted this in the past for 2.3.

Try this and let me know if it works:

{
  "query": {
    "bool": {
      "must": [
        {
          "function_score": {
            "query": {
              "match": {
                "name": {
                  "query": "A Name"
                }
              }
            },
            "min_score": 0.3
          }
        },
        {
          "function_score": {
            "query": {
              "match": {
                "address": {
                  "query": "1 Somewhere Street, Somewhereset, UK"
                }
              }
            },
            "min_score": 0.3
          }
        }
      ]
    }
  }
}
