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](https://github.com/elastic/elasticsearch-analysis-icu)). It can be installed by ```auto sudo bin/plugin install analysis-icu ``` [https://www.elastic.co/guide/en/elasticsearch/plugins/2.3/analysis-icu.html](https://www.elastic.co/guide/en/elasticsearch/plugins/2.3/analysis-icu.html) ---
