Created attachment 8399 [details] Screenshot All search fields are unique except in the Serials module. Here we have a ISSN field, and a Title field. The search is performed by the GetSubscriptions in C4/Serials.pm. The string typed in the Title zone is compared to the following fields: biblio.title subscription.callnumber subscription.location subscription.notes subscription.internalnotes The string typed in the ISSN field is compared to: biblioitems.issn subscription.callnumber (again!) The differences are not very significant, and the text accompanying the fields (saying just ISSN and Title) are not consistent with the actual search process. It would then probably be simpler to use only one input field, like it's done for other searches in Koha. We could do something closer to the "Search the Catalog" tab. Only one field, and a text saying "Enter search keywords:"
Seeing that this search zone now has 3 fields (EAN added), I guess reducing from 2 to 1 was not the way to go. I close this.
