[Koha] Multilingual Searching and ICU Chains

[Ere Maijala]

Hi Katrin,

Well, sort of. In the wiki
(https://wiki.koha-community.org/wiki/Elasticsearch) there's a whole
sentence on this:

"Note that all data field mappings will automatically handle alternate
script fields (880) for MARC 21 records."

Implementation details in bug 20244.
