ICU Chains Library

== ICU Chains Configuration and Customization ==
After ICU_chains_configuration, it may be necessary to modify words-icu.xml or phrases-icu.xml, based on the grammar of the language being searched.
See http://www.indexdata.com/zebra/doc/icuchain-files.html, http://www.indexdata.com/yaz/doc/yaz-icu.html, http://userguide.icu-project.org/transforms/general/rules and http://www.unicode.org/cldr/charts/latest/transforms/index.html

==== Thai ====
* Developer: Ajahn Ratanawanno -- http://lists.indexdata.dk/pipermail/zebralist/2015-August/002630.html
* File: words-icu.xml
* Language: Thai
* Locale: th
* Status: Untested
* Notes: According to the Koha mailing list thread, "The result in searching in Thai seems to be much better but still not really satisfy me if I compare to http://koha.library.tu.ac.th/, maybe I don't have search by keyword enable like their library.", so perhaps this needs some work. Perhaps the administrators at http://koha.library.tu.ac.th/ could share their words-icu.xml?
