[Koha] Records missing in OPAC

Hi everybody, I will explain my problem that I have with my database in koha. At the beginning I had a lot of records which don't have the good itemtype. The first move was changing the itemtype with a script. I changed the itemtype in the database (biblioitems table) and the marcxml also stored in the biblioitems table. The change worked but when I do a search in OPAC, the record that have changed are missing but they are present in the database. I did a rebuild of zebra but nothing changed. Did I do something wrong? Best regards! Laurent Spitaels laurent.spitaels@vki.ac.be www.vki.ac.be
