Hi,

Let me first explain my scenario.  
I am fetching data from RDBMS and pushing it into ElasticSearch.  
Fetched Results are in the form of List\<Map\<String,Object\> and i am preparing bulk index request like this:

```
BulkRequestBuilder bulkRequest = client.prepareBulk(); 
for (Map<String,Object> singleDataRow : ResultSet) 
{ 
       IndexRequest indexRequest = new IndexRequest("testindex","testtype",singleDataRow.getObject("NAME")); 
       bulkRequest.add(indexRequest); 
} 

bulkRequest.execute().actionGet(); 

```

My map\<String,Object\> = includes Map of string to string, string to big decimal, string to big integer etc.

But when i see the mapping of my testtype in testindex, all mapping of fields are of "type" : "string"

??

Why the fields does not maps to "type": "string" , or "type" : "long" , and even "type" : "date" because my map includes data like :

```
{ "BIRTHDATE" : "2015-03-05" , "NAME" : "deepankar" , "AGE" : "22" }
```
