How do you query and index for the list of fields in the index?

Thanks.

Using the Java API?

// Get cluster state
ClusterState clusterState =
client1.admin().cluster().prepareState().execute().actionGet().state();

// Get mapping from the cluster state
MappingMetaData mappingMetaData =
clusterState.metaData().index("my_index").mappings().get("my_type");

// Get the list of fields from the mapping
Map<String, Object> fields = (Map<String, Object>)
mappingMetaData.sourceAsMap().get("properties");
