[Koha] Request for documentation -- ICU chains

I did a bit of searching for ICU chains documentation on the Koha wiki, based on Fatone's post 'local language searching problem' ... and I wasn't really satisfied with what I found: The most complete documentation that I found was here: https://wiki.koha-community.org/wiki/Correcting_Search_of_Arabic_records There's also https://wiki.koha-community.org/wiki/Correcting_Search_of_Polish_records I've added https://wiki.koha-community.org/wiki/ICU_chains_configuration but I'm not enough of an expert to explain how to set up transliterate rules, which seem to be an important part of getting ICU to work to its fullest potential. Thanks, --Barton
