Neo4j Spatial 3.0.2: No index provider 'spatial' found - php

Question

I am trying to create a spatial database with neo4j 3.0.2 and neo4j-spatial for 3.0.2. I have installed the plugin and I have checked that the plugin is running with cURL curl -v http://neo4j:neo4j#localhost:7474/db/data/ which outputs following:

}* Closing connection #0
Now I can create a new simplePointLayer:
// define entity manager
$client = $this->get('neo4j.spatial_manager')->getClient();
// 1. Create a pointlayer
$request = $client->request('POST',
'/db/data/ext/SpatialPlugin/graphdb/addSimplePointLayer',
[
'json' => [
'layer' => 'geom',
'lat' => 'lat',
'lon' => 'lon',
],
]
);
var_dump($request);
This creates the spatial root node with the rTree. But when I now want to create a spatial index with following:
// 2. Create a spatial index
$request = $client->request('POST',
'/db/data/index/node/',
[
'json' => [
'name' => 'geom',
'config' => [
'provider' => 'spatial',
'geometry_type' => 'point',
'lat' => 'lat',
'lon' => 'lon',
],
],
]
);
var_dump($request);
I am confronted with the error-message:
"message" : "No index provider 'spatial' found.
What am I doing wrong? I have checked a lot of forums and so on, but the answer always seems to be to install the spatial plugin, which I have and it seems to be working according to the first output.
EDIT 15.06.2016
Whats weird is that I can add nodes to the rTree:
// Create a node with spatial data
$json = [
'team' => 'REDBLUE',
'name' => 'TEST',
'lat' => 25.121075,
'lon' => 89.990630,
];
$response = $client->request('POST',
'/db/data/node',
[
'json' => $json
]
);
$node = json_decode($response->getBody(), true)['self'];
// Add the node to the layer
$response = $client->request('POST',
'/db/data/ext/SpatialPlugin/graphdb/addNodeToLayer',
[
'json' => [
'layer' => 'geom',
'node' => $node,
],
]
);
$data = json_decode($response->getBody(), true);
var_dump($data);
And I can query the nodes through REST:
$request = $client->request('POST',
'/db/data/ext/SpatialPlugin/graphdb/findGeometriesWithinDistance',
[
'json' => [
'layer' => 'geom',
'pointX' => 89.99506,
'pointY' => 25.121260,
'distanceInKm' => 10,
],
]
);
$data = json_decode($request->getBody(), true);
var_dump($data);
But why is it not letting me create an index? Or does it do the indexing automatically? And if so, how can I query using CYPHER (in the web console for example)?
Any help would be appreciated! Cheers

Answer 1

The index provider was removed (back then it was the only means to provide integration with Cypher), in favor of user defined procedures for Spatial.
see: https://github.com/neo4j-contrib/spatial/blob/master/src/test/java/org/neo4j/gis/spatial/procedures/SpatialProceduresTest.java#L113
As this is a new major release (for 3.0) we found it sensible to remove the index provider.
