I have been able to do a search successfully. Here is a sample of my code:
ImmutableSettings.Builder settings = ImmutableSettings.settingsBuilder();
Client client = node.client();
client.prepareIndex("searchdata", "a", String.valueOf(123)).setSource(createJsonForExhibitor(object)).execute().actionGet();
It creates this structure on my drive
What are these all folders for? Can somebody explain to me what are these folders mapped to my index creation?
