title: ES function_score min_score for each function
body: <p>If I have in ElasticSearch query like:</p>
  
  <pre><code>{
    "query": {
      "function_score": {
        "query": {
          "match_all": {}
        },
        "boost": "5",
        "functions": [
          {
            "filter": {
              "match": {
                "test": "bar"
              }
            },
            "random_score": {},
            "weight": 23
          },
          {
            "filter": {
              "match": {
                "test": "foo"
              }
            },
            "weight": 42
          }
        ],
        "max_boost": 42,
        "score_mode": "max",
        "boost_mode": "multiply",
        "min_score": 42
      }
    }
  }
  </code></pre>
  
  <p>is it possible to set min_score for result from each function ?
  I would like to set 2 min_scores, one for bar second for foo.</p>
