Howdy,
Setup:
neo4j 2.1.2
spatial plugin: neo4j-spatial-0.12
I'm trying to query on spatial index that I created via php, the cypher
query works in a browser when I run neo4j standalone eg:
START n = node:geo_main('withinDistance:[41.061878,-73.79705, 2.2]') where
> n.city = "white plains" return n
gives back results.
However, when I stop neo4j and load the db from java:
...
graphDb = new GraphDatabaseFactory().newEmbeddedDatabase( DB_PATH );
...
...
public List<Node> listOfNodesWithinDist(double lat, double lon, double
maxDist) {
ExecutionEngine engine = new ExecutionEngine( graphDb, StringLogger.SYSTEM
);
ExecutionResult result = null;
List<Node> nodes = new ArrayList<Node>();
try ( Transaction tx = graphDb.beginTx(); )
{
result = engine.execute( "START n =
node:geom('withinDistance:["+lat+","+lon+", "+maxDist+"]') return n" );
ResourceIterator<Node> n_column = result.columnAs("n");
for ( Node node : IteratorUtil.asIterable( n_column ) )
{
nodes.add(node);
}
tx.success();
}
catch(org.neo4j.cypher.SyntaxException E){
System.out.println(E.getMessage());
}
return nodes;
}
I get:

I've also tried:
try (Transaction tx = graphDb.beginTx();) {
IndexManager index = graphDb.index();
// autoIndex = index.forNodes( "node_auto_index" );
geomIndex = index.forNodes("geo_main");
Map<String, Object> params = new HashMap<String, Object>();
params.put(LayerNodeIndex.POINT_PARAMETER, new Double[] { x, y });
params.put(LayerNodeIndex.DISTANCE_IN_KM_PARAMETER, maxDist);
IndexHits<Node> hits =
geomIndex.query(LayerNodeIndex.WITHIN_DISTANCE_QUERY, params);
for (Node stop : hits) {
nodes.add(stop);
}
tx.success();
} catch (org.neo4j.cypher.SyntaxException E) {
System.out.println(E.getMessage());
}
which gave me the same exception on line (geomIndex =
index.forNodes("geo_main");)
Is it a bug or am I doing something wrong ?
Thanks!!
