In Elasticsearch, the field 041 (subfields: a, d, e, i, j)
is not indexed with 'ln' search field. As a result, records cannot
be found when searching with languages present in 041 (but only
with the one from 008/35-37), and the languages are also missing
from the facet.
Subfields content (only relevant subfields):
$a - Language code of text/sound track or separate title
$d - Language code of sung or spoken text
$e - Language code of librettos
$i - Language code of intertitles
$j - Language code of subtitles
Test plan
=========
0. Have a test installation with Elasticsearch.
1. In ktd with its test data, make a biblio search for a language present
in 041 a/d/e/i/j but not in 008/35-37, e.g. for Japanese (with ln:jpn
or from Advance search). You will get no results.
2. Apply the patch, reindex with:
sudo koha-elasticsearch --rebuild -r -b kohadev
3. Repeat the test. You should get some records and also you should see
the Japanese language in the Languages facet.
