Hi,  
ES 2.4.0  
I want to enable the \_size field in elasticsearch mappings when i tried the following code

{  
"test": {  
"mappings": {  
"type1": {  
"\_size": {  
"enabled": true  
}  
}  
}  
}  
}

it is showing error like this

{  
"error": {  
"root\_cause": [  
{  
"type": "action\_request\_validation\_exception",  
"reason": "Validation Failed: 1: mapping type is missing;"  
}  
],  
"type": "action\_request\_validation\_exception",  
"reason": "Validation Failed: 1: mapping type is missing;"  
},  
"status": 400  
}
