I have solved in this way: Administration> System Preferences> Don't use the Zebra search engine. and then running: //usr/share/koha/bin/migration_tools/rebuild_nozebra.pl -s *********************************** ***** building BIBLIO indexes ***** *********************************** 2 Inserting records... 20 biblios done *********************************** ***** building AUTHORITIES indexes ***** *********************************** Inserting... authorities done/ i'm not sure if this way is the correct way, cause in the Adminstration panel i read: /It is recommended to use Zebra; the option to not use Zebra is deprecated and is not guaranteed to work. / What do you suggest?
