You can't map them to null, but you can map them to empty string. See the bottom of: http://git.koha.org/cgi-bin/gitweb.cgi?p=Koha;a=blob;f=etc/zebradb/etc/word-... I'm against mapping all periods to "" though, since there will be titles like "MyLife 2.0" or "Hacking Linux Kernel 2.6" where the period is essential to the semantics. It seems like what you might want to do is pull the period OUT of the "space" declaration. That may be worth considering for mainline Koha, after some testing. --Joe 2009/9/24 Cab Vinton <bibliwho@gmail.com>
Searching for "hms surprise" does not retrieve this record (title is "H.M.S. Surprise"):

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 :-)
