Does anyone have a step-by-step guide for adding the biblionumber to the zebra index? I need it to set up integration with a discovery service, so the discovery search can include both our Koha catalog holding and our subscribed online resources that are not in Koha. I've seen this link: https://wiki.koha-community.org/wiki/How_to_add_new_zebra_index But it's not clear on whether or why to use index_data_field vs index_sub_fields, how to pick the right attribute number, and other things like that, and I can't find any more complete documentation.
