Number of filter matches in array field

Elastic Stack Elasticsearch
1

I have a set of documents, each with an array of geo_points:

{
name: "Test Record",
locations: [
{
lat: 55.866638
lon: -4.289562
},
{
lat: 50.716633
lon: -1.878344
},
{
lat: 51.53587
lon: 0.696672
},
{
lat: 52.479473
lon: -1.909198
},
{
lat: 51.490692
lon: -0.224432
}
]
}

When using a geo_distance filter, is there a way to return, for each
document, the number of locations that matched the filter (I.E. were within
the search radius)?

Thanks!

I am wondering if you are not looking for Geo Distance Facets [1], do you?

I've had a go at using the geo_distance facet, but as far as I can tell it
returns the total number of documents that match each range, whereas I
would like the number of locations that match per-document.

As an example, if I queried with a geo_distance filter of "lat: 55, lon: -4" against
the above document, I would expect one of the location entries to match, so
the document would be returned, but I would like to know how many of the
location entries in that document match (even if the answer is only 1).

Could this be done using either highlighting or nested documents?

I had a go at using highlighting, but I can't find any documentation on
using it with a geo_distance filter, and I haven't been able to make it
work.

Nested / child documents could also work, but most queries that operate on
them seem to be focused on returning parents where any child matches a
parameter, whereas I want to return the parent, and those child documents
that caused the match.
