https://bugs.koha-community.org/bugzilla3/show_bug.cgi?id=43436 Bug ID: 43436 Summary: Elasticsearch doesn't order publication dates with 'u' correctly Initiative type: --- Sponsorship --- status: Product: Koha Version: 24.11 Hardware: All OS: All Status: NEW Severity: normal Priority: P5 - low Component: Searching - Elasticsearch Assignee: koha-bugs@lists.koha-community.org Reporter: katrin.fischer@bsz-bw.de QA Contact: testopia@bugs.koha-community.org Target Milestone: --- In MARC21, but also in UNIMARC as was mentioned on Mattermost, sorting by publication date doesn't work correctly. We use date-of-publication for sorting. In MARC21 this contains the information from 008, 4-10 (Date 1). These dates are fixed on 4 characters and can contain u for unknown parts of the date: 0201 1999 07uu We noticed this while working on a project that has a lot of manuscripts that can date back to before 1000 and have some uncertainty. The 07uu will sort as 7, which puts it off by a few hundred years. I experimented with the "Call number" type in the configuration as that has a sort configuration of "numerical: false". The results appear to be much better then. -- You are receiving this mail because: You are the assignee for the bug. You are watching all bug changes.
