I am trying to help a librarian in Brazil with this problem: Search found no results. They had fix zebra permissions according to this: https://wiki.koha-community.org/wiki/Fix_zebra_permissions and they had cleaned zebra search table according to this: https://stackoverflow.com/questions/26925152/reindexing-zebra-because-there-... But everytime they try to rebuild zebra, they get the following errors: [7]% sudo koha-rebuild-zebra -f -v -v library Warning: You passed -x which is already the default and is now deprecated Zebra configuration information ================================ Zebra biblio directory = /var/lib/koha/library/biblios Zebra authorities directory = /var/lib/koha/library/authorities Koha directory = /usr/share/koha/intranet/cgi-bin Lockfile = /var/lock/koha/library/rebuild/rebuild..LCK Use of uninitialized value $biblionumbertagfield in concatenation (.) or string at /usr/share/koha/bin/migration_tools/rebuild_zebra.pl line 215.
