Geo Mapping. How to index/query a non-point geo property?


dmitryzezix@...
 

Hello, guys!

I've tried to query complex geoshape, but got empty response. What am I doing wrong?

 

My query:

transaction = client.submit(
f"""
g.V().has("location", geoWithin(Geoshape.circle({lat}, {lon}, {radius})))
"""
)

 

Index creation:

transaction = client.submit(
"""
mgmt = graph.openManagement()
location = mgmt.makePropertyKey('location').dataType(Geoshape.class).cardinality(Cardinality.SINGLE).make()
mgmt.buildIndex('byLocation', Vertex.class).addKey(location, Mapping.PREFIX_TREE.asParameter()).buildMixedIndex('search')
mgmt.commit()
"""
)

 

Vertex creation:

transaction = client.submit(
f"""
g.addV("place").property("location", {graph_geoshape.to_janus_graph_property()})
"""
)

 

Schema looks like this:

[         '------------------------------------------------------------------------------------------------\n'

          'Vertex Label Name              | Partitioned | Static                                             |\n'

          '---------------------------------------------------------------------------------------------------\n'

          'place                          | false       | false                                              |\n'

          'location                       | false       | false                                              |\n'

          '---------------------------------------------------------------------------------------------------\n'

          'Edge Label Name                | Directed    | Unidirected | Multiplicity                         |\n'

          'place                          | SINGLE      | class org.janusgraph.core.attribute.Geoshape       |\n'

          '---------------------------------------------------------------------------------------------------\n'

          '---------------------------------------------------------------------------------------------------\n'

          'Graph Index (Edge)             | Type        | Unique    | Backing        | Key:           Status |\n'

          '---------------------------------------------------------------------------------------------------\n'

          '---------------------------------------------------------------------------------------------------\n'

          'Relation Index (VCI)           | Type        | Direction | Sort Key       | Order    |     Status |\n'

          '---------------------------------------------------------------------------------------------------\n']
