I want to use ICU Collation plugin for sorting Persian in ElasticSearch-2.3.3, but it seems that the last version of "elasticsearch-analysis-icu" is 2.7 and it is compatible with 1.7 version of ElasticSearch. Can every body help me to solve this problem?
The analysis-icu plugin is now part of the main Elasticsearch repo (as it states here). It can be installed by
sudo bin/plugin install analysis-icu
