Re: indexQuery error: Index with name [ ] is unknown or not configured properly

Hi Rajdeep,

Just two suggestions:
  1. factory.open() takes some default graph that contains vertices?
  2. the mgmt object also has some(...) awaitStatus() method that must return the right value before the index can be used, see the examples in the ref docs

Cheers,     Marc

I am using indexQuery (see code below) and getting the following error:

    val factory = JanusGraphFactory.build().set("storage.backend","cassandra").set("storage.hostname","localhost")


    factory.open()


     val mgmt = graph.openManagement();
       


      val property_key = mgmt.getOrCreatePropertyKey(propertyKeyIdentifier)
     


      println("** Started Indexing now **")


      mgmt.buildIndex("vertexByText", classOf[Vertex]).addKey(property_key).buildCompositeIndex()
      mgmt.commit()
      println("** Finsihed Indexing **")
     
      // try getting the index
      val retrievedIndex = mgmt.getGraphIndex("vertexByText")


      graph.addVertex(propertyKeyIdentifier, "Mass")

     


      // This does not work for some reason
      val result = graph.indexQuery(retrievedIndex.name(), "Mass").vertices().iterator()

What is causing it to fail even when the ,getGraphIndex  is able to retrieve the index?
