Hi all Recently i ran koha version 3.0200.004 on ubuntu server . I imported a batch of 3895 marc records , all records are proper . When i searched by itemtype it resulted 113 records fof English books , and 102 for Arabic theses . I ran zebra rebuilding . I dont know what extra settings should i do ??? Thanks in advance Izzeldin Mogawir
