            Bug ID: 27010
           Summary: Warnings produced by Elasticsearch QueryBuilder.pm
 Change sponsored?: ---
           Product: Koha
           Version: master
          Hardware: All
                OS: All
            Status: NEW
          Severity: minor
          Priority: P5 - low
         Component: Searching - Elasticsearch
          Assignee: koha-bugs at lists.koha-community.org

In Koha/SearchEngine/Elasticsearch/QueryBuilder.pm we get following warnings:

> [WARN] Use of uninitialized value $f in hash element at /usr/share/koha/lib/Koha/SearchEngine/Elasticsearch/QueryBuilder.pm line 605.
> [WARN] Use of uninitialized value $d in hash element at /usr/share/koha/lib/Koha/SearchEngine/Elasticsearch/QueryBuilder.pm line 605.

This seems to be due to _convert_sort_fields() not checking whether my ( $f, $d
) get initialized by the regex before using them in the map function:

> 601     grep { $_->{field} } map {
> 602         my ( $f, $d ) = /(.+)_(.+)/;
> 603         {
> 604             field     => $sort_field_convert{$f},
> 605             direction => $sort_order_convert{$d}
> 606         }
