Hola buenas tardes a toda la comunidad Koha-es. Queria ver si me podrian ayudar con un problema. Para darles contexto, estuve migrando koha de un servidor debian a otro. En tal caso pude levantar las páginas intranet y opac , pero tengo dificultad al intentar buscar el contenido. No me aparece ningún error ni nada, simplemente al momento de buscar no aparece nada.  Tengo la Teoría de que el principal problema está al momento de reindexar el contenido dentro del servidor (sudo koha-rebuild-zebra -f -v).
Cuando intenta exportar las biblio aparecen estos errores: 
1Use of uninitialized value $tag in hash element at /usr/share/perl5/MARC/Record.pm line 202.
Use of uninitialized value $tag in regexp compilation at /usr/share/perl5/MARC/Record.pm line 206.
