Oh indeed. I think its what is in : https://bugs.koha-community.org/bugzilla3/show_bug.cgi?id=26051 Best regards Le 20/01/2021 à 23:51, Zeno Tajoli a écrit :
Hi to all,
in default ES setup sort by call_number is not working. Inside Koha/SearchEngine/Elasticsearch/QueryBuilder.pm, routine _convert_sort_fields there is this fix convection:
call_number => 'local-classification',
'call_number' is the string used in the search abstraction level for index used for sort with call numbers
'local-classification' is the name of the ES index selected for sorting by call numbers
I think that the selection of 'local-classification' as standard sort index for call numbers is not a good idea. I think is better to use the ES index 'cn-sort' that is connect with 952$6 [MARC21] and 995$s[Unimarc] and the mysql field items.cn_sort. items.cn_sort is the normalized form of the call number used for sorting.
I can write a patch to connect cn-sort with 'call_number' and fix also default setup of admin/searchengine/elasticsearch/mappings.yaml, inserting 'cn-sort' as sortable.
What do you think ?
Cheers Zeno Tajoli
