You can try using function_score:

{
  "query": {
    "function_score": {
      "query": {
        "match_all": {}
      },
      "functions": [
        {
          "filter": {
            "term": {
              "testField": "testValue"
            }
          },
          "boost_factor": 15
        }
      ]
    }
  }
}
