Neo4j Spatial work for POST but not work cypher

Question

I have used Neo4j 3.0.4 + Spatial.

I am working with curl, and I have make this calls:

addSimplePointLayer,(create nodes),addNodeToLayer

In this point, I try:

findGeometriesWithinDistance

And work perfectly (I have need change lat,lon by lon,lat...)

But I need use in cypher, for example:

START n=node:geom('withinDistance:[40.39742917035895,-3.495200140744832, 100.0]') 
  WITH n 
  WHERE n:TypeX
  RETURN n;

This never return results because "geom" is empty. I haven't any index, I try to create a new index with provider "spatial", and not work (i have read that is option was remove).

Can I put all nodes of TypeX in geom index?, or Can I use withinDistance without index? (I think in where is not posible use this)

I have found this: MATCH (r:Restaurant) WHERE distance(point(r),point({latitude:40.39682978190974,longitude:-3.4897354662994173})) < 2*1000 RETURN r It work withouth Spatial, Is it a good option? — David González

The index provider has been removed in the spatial extension for Neo4j 3.x in favor of using procedures. Instead you can call the procedures directly from Cypher. For example:

To create a SimplePointLayer:

CALL spatial.addPointLayer("geom")

Then to add Restaurant nodes to the layer:

MATCH (r:Restaurant) WITH collect(r) AS restaurants
CALL spatial.addNodes("geom", restaurants) YIELD node
RETURN count(*)

Then to perform a within distance query:

CALL spatial.withinDistance("geom",{latitude: 40.39742917035895,longitude:-3.495200140744832}, 100.0) YIELD node AS restaurant
RETURN restaurant

Documentation for these procedures is still in progress, but there is some documentation on the Github project README and in this post.
