#' @description
#' Submit a search request for `VariantSets`
#'
#' @param con list; required: TRUE; BrAPI connection object
#' @param callSetDbIds vector of type character; required: FALSE; The `CallSets`
#'    to search as specified by the unique database identifier(s); default:
#'    "", when using multiple values supply as c("value1",
#'    "value2").
#' @param studyDbIds vector of type character; required: FALSE; List of unique
#'    database study identifiers to search for; default: "", when
#'    using multiple values supply as c("value1", "value2").
#' @param studyNames vector of type character; required: FALSE; List of study
#'    names to filter search results; default: "", when using multiple
#'    values supply as c("value1", "value2").
#' @param variantDbIds vector of type character; required: FALSE; The unique
#'    Variant database identifiers to search.; default: "", when using
#'    multiple values supply as c("value1", "value2").
#' @param variantSetDbIds vector of type character; required: FALSE; The unique
#'    `VariantSet` database identifiers to search.; default: "", when
#'    using multiple values supply as c("value1", "value2").
#' @param page integer; required: FALSE; Used to request a specific page of data
#'    to be returned. The page indexing starts at 0 (the first page is
#'    `page = 0`). Default is `0`.
#' @param pageSize integer; required: FALSE; The size of the pages to be
#'    returned. Default is `1000`.
#'
#' @details Submit a search request for `VariantSets`. 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).
