[Koha] Minor search detail

Searching for "hms surprise" does not retrieve this record (title is "H.M.S. Surprise"): http://splnh.kohalibrary.com/cgi-bin/koha/opac-detail.pl?biblionumber=19316 This search does work of course: "h.m.s. surprise". Explanation I was given is that zebra does not support mapping characters to NULL. If anyone has any pull with the zebra folks, this is something that they should address. We added a 246 (variant title form) to take care of the problem. Of course, have not idea how many other titles in our catalog might be affected by this quirk :-) Cheers, Cab Vinton, Director Sanbornton Public Library Sanbornton, NH
