Hi Layale, Depending on what type of installation you have, you would probably have to edit /etc/koha/zebradb/marc_defs/marc21/biblios/biblio-koha-indexdefs.xml and then transform it into biblio-zebra-indexdefs.xsl (or directly edit biblio-zebra-indexdefs.xsl). But -- again, depending on the type of your installation -- be aware of possible problems with upcoming updates. Good luck!

The search is currently searching other subfields like c and returning non-relevant results. What files should I edit in this case? Thank you in advance, Regards. _______________________________________________ Koha mailing list http://koha-community.org Koha@lists.katipo.co.nz https://lists.katipo.co.nz/mailman/listinfo/koha
