Apply geo distance filter on nested field - elasticsearch

Question

My mapping contains a nested field like this:
"Locations": {
"type": "nested",
"properties": {
"Name": {
"type": "string"
},
"GeoPoint": {
"type": "geo_point"
}
}
}
So basically what I'm trying to do is store some additional attributes with every location of the document.
Unfortunately, it looks like this won't work with a geo distance filter:
GET /myIndex/myType/_search
{
"filter": {
"geo_distance": {
"distance": "100 mi",
"Locations.GeoPoint": {
lat: 40.70,
lon: -74.00
}
}
}
}
won't return the any results, whereas the filter works flawlessly if the GeoPoint is directly on the document itself instead of on the nested field:
GET /myIndex/myType/_search
{
"filter": {
"geo_distance": {
"distance": "100 mi",
"GeoPoint": {
lat: 40.70,
lon: -74.00
}
}
}
}
Is there any way to make geo distance filter work with geo_point on the nested field?

Answer 1

A nested filter does the job:
GET /myIndex/myType/_search
{
"filter" : {
"nested" : {
"path" : "Locations",
"filter" : {
"geo_distance": {
"distance": "100 mi",
"GeoPoint": {
"lat": 40.70,
"lon": -74.00
}
}
}
}
}
}

An update for ElasticSearch 5.5 users, #Max's answer has been deprecated for the Nested Filter and Nested Query feature using the dot notation instead of explicitly wrapping a "nested" field around your query.
For example:
{
"query": {
"nested" : {
"path" : "obj1",
"score_mode" : "avg",
"query" : {
"bool" : {
"must" : [
{ "match" : {"obj1.name" : "blue"} },
{ "range" : {"obj1.count" : {"gt" : 5}} }
]
}
}
}
}
}
