Hi Jason, I tried to do that. JanusGraphManagement janusGraphManagement=janusGraph.openManagement(); janusGraphManagement.set("index.search.index-name",

Hi Jason, Thanks for quick response. Will try this and it should work. Thanks Akshaya

Doh, you're right Daniel. Meta-properties do not support cardinality, only vertex properties do.
