I enter the code like elasticsearch example, but the coerce result is wrong.

PUT my\_index  
{  
"settings": {  
"index.mapping.coerce": true  
},  
"mappings": {  
"my\_type": {  
"properties": {  
"number\_one": {  
"type": "integer"  
},  
"number\_two": {  
"type": "integer",  
"coerce": false  
}  
}  
}  
}  
}

PUT my\_index/my\_type/1  
{ "number\_one": "10" }

GET my\_index/my\_type/\_search

the result:

{  
"took": 7,  
"timed\_out": false,  
"\_shards": {  
"total": 5,  
"successful": 5,  
"failed": 0  
},  
"hits": {  
"total": 1,  
"max\_score": 1,  
"hits": [  
{  
"\_index": "my\_index",  
"\_type": "my\_type",  
"\_id": "1",  
"\_score": 1,  
"\_source": {  
"number\_one": "10"  
}  
}  
]  
}  
}

no convertion happened, why?
