title: GeoPoint with Spring Data ElasticSearch is giving error : QueryParsingException[field [location] is not a geo_point field]
body: <p>I have elasticsearch entity in spring as below : </p>
  
  <pre><code>@Document(indexName = "cities_in", type = "cities")
  public class CityDocument {
  
  @Id
  private String id;
  
  @Field(type = FieldType.String)
  private String city;
  
  @Field(type = FieldType.Object)
  @GeoPointField
  private GeoPoint location;
  }
  </code></pre>
  
  <p>but when I see mapping using curl <code>curl -s -XGET 'http://localhost:9200/cities_in/cities/_mapping?pretty=1'</code> I get output as:</p>
  
  <pre><code>  {
     "cities_in" : {
     "mappings" : {
      "cities" : {
        "properties" : {
          "city" : {
            "type" : "string"
          },
          "id" : {
           "type" : "string"
        },
        "location" : {
          "properties" : {
            "geohash" : {
              "type" : "string"
            },
            "lat" : {
              "type" : "double"
            },
            "lon" : {
              "type" : "double"
            }
          }
          }
          }
       }
     }
   }
  }
  </code></pre>
  
  <p>and when hit I query I get below error:</p>
  
  <pre><code>{
   "error" : {
  "root_cause" : [ {
    "type" : "query_parsing_exception",
    "reason" : "No query registered for [geo_point]",

    "line" : 1,
    "col" : 33
  } ],
  "type" : "search_phase_execution_exception",
  "reason" : "all shards failed",
  "phase" : "query",
  "grouped" : true,
  "failed_shards" : [ {
    "shard" : 0,
    "index" : "cities_in",
    "node" : "4jGBH3m4SkqNnBwC196hTw",
    "reason" : {
      "type" : "query_parsing_exception",
      "reason" : "No query registered for [geo_point]",
      "index" : "cities_in",
      "line" : 1,
      "col" : 33
    }
  } ]
    },
    "status" : 400
   }

  <p>Why is location type not <code>geo_point</code>?
  How to manage geopoint with spring? </p>
