Hi,  
I'm a newbie to the ELK stack and I'm probably stuck due a syntax error.  
Any help would be most appreciated.

I've installed ES and I'm trying to create a mapping for my index to fit the following json:  
{  
"facets": [  
{  
"name": "https://web\_address\_example.aspx",  
"results": [  
{  
"count": 13995  
},  
{  
"average": 2.188390496605931  
},  
{  
"max": 157.3  
},  
{  
"min": 0.391  
}  
]  
}  
}

The mapping syntax I've tried so far but fails is:

post /db\_average\_response\_time/\_mappings/  
{  
"mapping":  
{  
"facets" :  
{  
"fields" :  
{  
"name" :  
{  
"type" : "text"  
},  
"results" :  
{  
"fields" :  
{  
"count" :  
{  
"type" : "integer"  
},  
"average" :  
{  
"type" : "double"  
},  
"max" :  
{  
"type" : "double"  
},  
"min" :  
{  
"type" : "double"  
}  
}  
}  
}  
}  
}  
}
