Description
$geoNear sorts documents by their distance from a given query point. Conceptually it both:
1. computes the distance, storing the result in the document metadata
2. sorts by that distance
The second step we can already express with $sort $meta.
Let's expose the first step as a new internal DocumentSource. The syntax might look something like this:
{$_internalComputeGeoNearDistance: {
|
near: <point>,
|
key: <fieldname>,
|
}}
|
Then a future ticket (SERVER-58602) can use this to allow $geoNear to execute anywhere in a pipeline.
