After marking an item "withdrawn", that item does not show as withdrawn in the Staff client in a summary list of a keyword search (search.pl). If you click on the title in the Staff client to get details (detail.pl) the status displays properly, as do the summary list and detail pages in the OPAC client (opac-search.pl and opac-detail.pl).
I cannot reproduce this problem in the latest 3.18.x or in more recent versions.
