In boolean should statement , you can give multiple queries of should and boost certain query over other.

curl -XGET localhost:XXXX/index/type/_search?pretty -d '{
  "query": {
    "bool": {
      "should": [
        {
          "match_phrase": {
            "title": "installer stack",
            "boost": 3
          }
        },
        {
          "match": {
            "title": "installer",
            "boost": 2
          }
        },
        {
          "match": {
            "title": "stack",
            "boost": 1
          }
        }
      ]
    }
  }
}'
