Currently, the Journal Title facet in Primo only applies to records from the Central Discovery Index (CDI), excluding locally cataloged article records and those imported from external sources such as institutional repositories. This behavior leads to inconsistent and confusing results for end users, especially when using a blended scope that includes both CDI and local records.

Problem:
Users conducting searches—particularly in the local language—often retrieve a significant number of local article records. Despite these articles being published in journals, their journal titles do not appear in the Journal Title facet.
Users are unaware of the distinction between CDI and local records and perceive the facet as broken or unreliable. This undermines user trust and the usability of the facet as a filtering tool.

Our question is to
- extend facet generation logic to include journal titles from local records (Alma-records and imported via import profile)
- or if this is not possible, allow customers to customize the facet in order to include local records.

This would ensure:
- Consistent and complete facet behavior across all indexed content.
- Improved user experience and trust in the system.
- Better support for institutions that rely heavily on local cataloging or repository imports.
