[Koha] Koha: staff client searching by card number

Everyone, Another newbie question: Is there a way in the staff client to search by the exact card number? It seems to be using wild cards before and after. For example, a search for "643" pulls up 1643", "36431" and everything else that contains "643" with 643 in the list. We want it to pull up only the one 643. I'm assuming it isn't acceptable to change member.pl? Thanks in advance. -- Linda Culberson lculber@mdah.state.ms.us Archives and Records Services Division Ms. Dept. of Archives & History P. O.
