[Koha] Fix for Z3950 search by title

Hi Paul, I reviewed the logs of the irc meeting from yesterday, and you mentioned finding and fixing a bug in the Z3950 search module when searching by title. I have noticed some really strange results when searching by title in 2.2.7. Does your fix apply to 2.2.7, and could you please provide the details of how to get the fix? Thanks, Rob
