Bug ID: 33206
Summary: Bad title__sort made of multifield 245
Change sponsored?: ---
Product: Koha
Version: master
Hardware: All
OS: All
Status: NEW
Severity: enhancement
Priority: P5 - low
Component: Searching - Elasticsearch
Assignee: [email protected]
Reporter: [email protected]
In MARC 21, having title search field defined in mappings.yaml as 245abp (more
than one subfield), the Koha generated title__sort will have not only $a, but
also other subfields cut by ind2 characters, i.e.:
245 04 $a Die Renaissance : $b Architektur, Plastik, Malerei, Illustrationen,
Zeichnungen
becomes as title__sort:
Renaissance : itektur, Plastik, Malerei, Illustrationen, Zeichnungen
instead of:
Renaissance : Architektur, Plastik, Malerei, Illustrationen, Zeichnungen
This is because copying an array of pointers in Perl causes you to point to the
same (anonymous) element. Therefore, the intended modification only for
subfield "a" (Koha/SearchEngine/Elasticsearch.pm, ~line 1157) causes in fact
modification for all the subfields sharing the same mapping definition and
introduction of the nonfiling_characters_indicator to all subfields 245 when
processing 245abp. And this is obviously not what is intended.
