#' @param externalReferenceSources vector of type character; required: FALSE;

#'
#' @details Advanced searching for the programs resource. Function will return
#'    either the search results (Status 200 for an immediate response) or a
#'    `searchResultsDbId` (Status 202 for both a saved and an asynchronous
#'    search).
