I use _function\_score_ to create my custom score based on the distance  
between the user and a place.

"function\_score": {  
"functions": [  
{  
"gauss": {  
"location": {  
"origin": "47.3942675,0.6949399",  
"scale": "40km",  
"decay": 0.5  
}  
}  
}  
],  
"query": { ... // my query

It works quite well. But I wan't ElasticSearch to return the distance (in  
km) for each result. I added:

"sort" : [  
{  
"\_geo\_distance" : {  
"location" : [0.6949399,47.3942675],  
"order" : "asc",  
"unit" : "km"  
}  
}  
]

I was wondering... is it the proper way to do it ? Does it force ES to  
calculate the distance twice (for scoring & sorting) ? or is it just ok ?
