I left some feedback: https://github.com/ryantxu/lucene-solr/commit/4792f0c13cb4d99cddf92c406a127ce08e04c715#diff-6ead4e8deaf560600de90a67c0b37e57R2126
> Suppor GeoJSON response format
> ------------------------------
>
> Key: SOLR-8814
> URL: https://issues.apache.org/jira/browse/SOLR-8814
> Project: Solr
> Issue Type: New Feature
> Components: Response Writers
> Reporter: Ryan McKinley
> Priority: Minor
> Fix For: master, 6.1
>
> Attachments: SOLR-8814-add-GeoJSONResponseWriter.patch
>
>
> With minor changes, we can modify the existing JSON writer to produce a GeoJSON `FeatureCollection` for ever SolrDocumentList. We can then pick a field to use as the geometry type, and use that for the Feature#geometry
> {code}
> "response":{"type":"FeatureCollection","numFound":1,"start":0,"features":[
> {"type":"Feature",
> "geometry":{"type":"Point","coordinates":[1,2]},
> "properties":{
> ... the normal solr doc fields here ...}}]
> }}
> {code}
> This will allow adding solr results directly to various mapping clients like [Leaflet|http://leafletjs.com/]
> ----
> This patch will work with Documents that have a spatial field the either:
> 1. Extends AbstractSpatialFieldType
> 2. has a stored value with geojson
> 2. has a stored value that can be parsed by spatial4j (WKT, etc)
> The spatial field is identified with the parameter `geojson.field`
