Hi,

I would like to know if it's possible to create a Range Facet on  
script\_fields ?

Here is my request :

{  
"fields" : ["id", "name"],  
"query" : {  
"text" : { "type": "mytype" }  
},  
"script\_fields" : {  
"average" : {  
"script" : "(\_source.rate1 + \_source.rate2) / 2"  
}  
},  
"facets" : {  
"average" : {  
"range" : {  
"field" : "average",  
"ranges" : [  
{ "to" : 4 },  
{ "from" : 4, "to" : 6 },  
{ "from" : 6, "to" : 8 },  
{ "from" : 10 }  
]  
}  
}  
}  
}

This request fails ... I've tried with "script\_fields" : "average",  
"key\_field" : "average", but no result ...

It's possible on Term Facet, but I didn't find how to make it on Range  
Facet ...  
Is it possible ?

Thanks in advance.  
Jérémy

script fields are only applicable to the top N docs that you get back (computed and returned), not for the total hits you get. Facets work on all the hits (and because of that, using \_source is not recommended, because it means you load it and parse it for each hit out of the total hits). Check the range facet docs: [Elasticsearch Platform — Find real-time answers at scale | Elastic](http://www.elasticsearch.org/guide/reference/api/search/facets/range-facet.html), you can have an option to provide a key script and a value script.
