I have a parent and an array of nested objects called children. I am getting lat and lng(longitude) from my sql join query. I want to create geo\_point in nested objects of parents contained in an array using lat and lng. I tried different methods but couldn't do it.

filter {  
aggregate {  
task\_id =\> "%{id}"  
code =\> "  
map['id'] = event.get('id')  
map['name'] = event.get('name')  
map['lat'] = event.get('lat')  
map['lng'] = event.get('lng')  
map['list'] ||=   
map['children'] ||=   
if (event.get('child\_id') != nil)  
if !( map['list'].include? event.get('child\_id') )  
map['list'] \<\< event.get('child\_id')  
map['children'] \<\< {  
'child\_id' =\> event.get('child\_id'),  
'street\_address' =\> event.get('street\_address')  
}  
end  
end  
event.cancel()  
"  
push\_previous\_map\_as\_event =\> true  
timeout =\> 15  
}  
mutate {  
add\_field =\> { "[children][location][lat]" =\> "%{lat}" }  
add\_field =\> { "[children][location][lon]" =\> "%{lng}" }  
}  
mutate {  
convert =\> {"[location][lat]" =\> "float"}  
convert =\> {"[location][lon]" =\> "float"}  
}  
}

Do you have an index mapping template that tells elasticsearch that the [location] and [children][location] fields are geo\_points?

Hi Badger, I have read your answer and thanks for all the help.  
However I solved this problem by setting up a mapping for geo\_point.  
Now I want to sort results according to some field in nested objects but I am not able to do. I have an array of nested objects with field cost.
