Boosting specific field value in Elastic search

Hi I need to boost the documents based on the on a particular value of a field.. My documents contains a field called Region.. Based on the value present in the region i need to boost my documents.. These are my documents

{
    "title":"INOX: Malleshwaram - Mantri Square",
    "region":"Bangalore"
  }

    {
    "title":"INOX: Bund Garden Road",
    "region":"Pune"
   }

   {
    "title":"INOX: Glomax Mall, Kharghar",
    "region":"Mumbai"
  }

I have tried to use rescore query in my query which look like this

"rescore" : {
      "query" : {
          "score_mode":"total",
          "query_weight" : 2.5,
         "rescore_query_weight" : 0.5,
         "rescore_query" : {
            "match" : {
               "region" : {
                  "query" : "mumbai",
                   "slop" : 2
               }
            }
         }
      }
   }
}

But its not working properly as required..Is there any way to solve this?.. Thanks in advance!

Why rescoring, all you need is boosting. Based on the query type you are using, boosting is possible in 

"query_string": {
  "fields":["region^56"],
  "use_dis_max" : true,
      "query": "mumbai"
}

where ^56 is the boosting value.

You can also use as mentioned here http://www.elasticsearch.org/guide/en/elasticsearch/reference/current/query-dsl-boosting-query.html

If you are using the bool query you can use boost like this to boost all queries

{
"bool" : {
    "must" : {
        "term" : { "region" : "mumbai" }
    },
    "boost" : 25.0
}

}
