Neo4j+Gremlin : Trouble with T.gte and floating point node attributes
- by letronje
For a type of nodes in my graph, attribute values for an attribute(named 'some_count') is either missing or an integer or a float. I'm trying to write gremlin to filter these nodes based on minimum value for this attribute.
I first verified that the values are indeed present by firing the following gremlin
g.v(XXX)._().in('category').hasNot('some_count', T.eq, null).back(1).some_count
Next,
I tried filtering by exact value and that works and show me the matching nodes or gives an empty array if there is no match
g.v(XXX)._().in('category').hasNot('some_count', T.eq, null).back(1).has('some_count', T.eq, 120000.0d)
But the following query that uses the 'greater than or equal to' comparator doesn't work.
g.v(XXX)._().in('category').hasNot('some_count', T.eq, null).back(1).has('some_count', T.gte, 1.0d) this returns nil (I'm querying via ruby/rails using Neo4j AR Adapter )
Instead of returning an empty array for no match, it returns a nil, which tells me something could be wrong with the query itself. I'm running neo4j community server 1.8.
Is there a way I can ask Neo4j to log errors/queries, to see what could be going wrong ?
