Just with the core api.
db.index().forNodes("spatial").add(node, "dummy","dummy");
depending on the config
node has to have geo-properties (lat, lon)
or
node has to have geo-properties (point in well-known-text (wkt))
SDN uses this index-config:
MapUtil.stringMap(
IndexManager.PROVIDER, "spatial", "geometry_type" ,
"point","wkt","wkt")
and "wkt" as property-name for the well-known-text-point.
