ICU Analysis Plugin

The ICU Analysis plugin integrates the Lucene ICU module into elasticsearch, adding extended Unicode support using the ICU libraries, including better analysis of Asian languages, Unicode normalization, Unicode-aware case folding, collation support, and transliteration.

This plugin can be installed using the plugin manager:

sudo bin/plugin install analysis-icu

The plugin must be installed on every node in the cluster, and each node must be restarted after installation.

This plugin can be downloaded for offline install from https://download.elastic.co/elasticsearch/release/org/elasticsearch/plugin/analysis-icu/2.4.6/analysis-icu-2.4.6.zip.

The plugin can be removed with the following command:

sudo bin/plugin remove analysis-icu

The node must be stopped before removing the plugin.
