      public IndexedBackend(ClusterParams clusterParams, Dispatcher dispatcher)
      Creates a Fastsearcher.
      Parameters:
      dispatcher - the dispatcher used (when enabled) to send summary requests over the rpc protocol. Eventually we will move everything to this protocol and never use dispatch nodes. At that point we won't need a cluster searcher above this to select and pass the right backend.
      clusterParams - the cluster number, and other cluster backend parameters
