Bug ID: 43287
Summary: Branch search filter fails to retrieve title-level
analytics (773$w / 001) without items
Initiative type: ---

Product: Koha
Version: 25.11

Description:
In a multi-branch environment, when cataloging component parts or analytical
records (for monographs or serials) linked strictly at the title level—using
field 001 in the host/parent record and field 773$w in the analytical record,
without creating items directly on the analytical record—limiting a search by a
specific library branch fails to return the analytical records.
Analytical records are only retrieved when searching under 'All libraries'.
When filtering by a specific branch, the search engine excludes the analytical
record because it lacks its own item, ignoring the fact that the host/parent
record has items attached to that branch.
Steps to Reproduce:
1. Setup: A Koha instance with at least two branches (e.g., Branch A and Branch
B).
2. Host Record: Create or select a host/parent record (monograph or serial)
with a control number in field 001 (e.g., 12345). Attach at least one item to
this host record assigned to Branch A.
3. Analytical Record: Create an analytical record (article or chapter) linked
to the host record via 773$w containing the host's 001 control number (e.g.,
773$w = 12345). Do NOT attach any items directly to this analytical record.
4. Search: Go to OPAC or Staff Interface, set the library search filter/limit
to Branch A, and search for terms matching the title or author of the
analytical record.
Actual Result:
The analytical record is not returned when filtering by Branch A. It is only
retrieved when searching across 'All libraries'.
Expected Result:
When filtering by a specific branch (Branch A), the search engine should
retrieve analytical records linked via 773$w to host records that have items at
that branch, indexing/inheriting branch availability from the host record.
Additional Context / Notes:
- Use case: In centralized or title-level analytical cataloging workflows,
attached items should not be duplicated for every single component
part/analytic. Branch ownership is determined by the existence of items on the
host record.
- Indexing behavior: The branch index filter (homebranch / holdingbranch)
currently evaluates only item fields present on the record being indexed,
without resolving the 773$w -
There is a similar but unresolved issue already reported: Bug 19331.
Thank you very much.
