Find closest GeoJSON polygon to point when point lies outside of all polygons in Elasticsearch

问题

Using Elasticsearch, say I have documents of GeoJSON polygons. I'm using the percolator (ala How to know if a geo coordinate lies within a geo polygon in elasticsearch?) to find if a point lies within a polygon. That works great!

Is there any way in Elasticsearch to determine

1. If a point lies outside of all polygons
2. What the closest polygon that to that point?
3. Return that polygon
