I want to boost the score of records that are close to some geo position.  
Elastic has filters for geo, but that just includes or excludes records.  
Is there a way to manipulate the score using the distance? I know there  
is a custom\_score query where I could specify something like "script" : "\_score

- doc['my\_numeric\_field'].value". The question is, how would I use the  
distance in the calculation, and not the value of the numeric field?

You can calculate the distance using the following  
expression: doc['your\_geo\_field'].distanceInKm(lat, lon) and then use it to  
figure out the boost factor. For example this script: "\_score \*  
(doc['your\_geo\_field'].distanceInKm(40, -70) \< 100 : 2.0: 1.0)" will apply  
boost 2.0 to all records that are located within 100km from the location  
(40, -70). Alternatively, you can use Custom Filters Score Query[http://www.elasticsearch.org/guide/reference/query-dsl/custom-filters-score-query.html](http://www.elasticsearch.org/guide/reference/query-dsl/custom-filters-score-query.html)to boost records using a geo\_distance filter. So, a faster equivalent of  
the above expression would be:

{  
"custom\_filters\_score": {  
"query": {  
.... some query ....  
},  
"filters": [{  
"filter": {  
"geo\_distance": {  
"distance": "100km",  
"pin.location": {  
"lat": 40,  
"lon": -70  
}  
}  
},  
"boost": 2.0  
}],  
"score\_mode": "first"  
}  
}
