 #' @param KorAPUrl instead of providing the query and vc string parameters, you can also simply copy a KorAP query URL from your browser and use it here (and in \code{KorAPConnection}) to provide all necessary information for the query.

 #' @return A KorAP query object that, among other information, contains the total number of results in \code{$meta$totalResults}. The resulting object can be used to fetch all query results (with \code{\link{KorAPFetchAll}}) or the next page of results (with \code{\link{KorAPFetchNext}}). Please make sure to check \code{$collection$rewrites} to see if any unforseen access rewrites of the query's virtual corpus had to be performed.
