Match phrase prefix query seems to ignore boost value.

[mohittt8]

There seems to be no effect on score on changing boost value on match_phrase_prefix query.

My query is:

 "query": {
        "bool": {
            "should": [
                {"match_phrase_prefix": {
                        "firstName": {
                            "query": "is", 
                            "boost":2.0
                        }
                    }} ,
                    {"match_phrase_prefix": {
                        "userName.raw": {
                            "query": "Tiv", 
                            "boost":4.0
                        }
                    }}
              ]
        }
    }

I am trying this on Elasticsearch-1.7

Boost does seem to be ignored by the match_phrase_prefix query:

PUT t/t/1
{
  "one": "foo",
  "two": "bar"
}

GET t/_search?explain
{
  "query": {
    "bool": {
      "should": [
        {
          "match": {
            "one": {
              "query": "foo",
              "boost": 5
            }
          }
        },
        {
          "match_phrase_prefix": {
            "two": {
              "query": "bar",
              "boost": 50
            }
          }
        }
      ]
    }
  }
}
