Amazon OpenSearch Service adds support for four new language analyzer plugins- Pinyin (Chinese), STConvert Analysis (Chinese), Nori (Korean), and Sudachi (Japanese) plugins. These are available as optional plugins that you can associate with your OpenSearch Service clusters.

Amazon OpenSearch Service previously supported language analyzer plugins such as IK (Chinese) Analysis, Kuromoji (Japanese), Seunjeon (Korean), amongst several others. We are now adding support for Nori (Korean), Sudachi (Japanese), Pinyin (Chinese), and STConvert Analysis (Chinese). These new plugins are available as a new package type, ‘ZIP-PLUGIN’, along with the previously supported ‘TXT-DICTIONARY’ package type. You can use the ‘Packages’ section of the Amazon OpenSearch Service console to associate these plugins to your cluster, or use the AssociatePackage API.

Pinyin, STConvert, Nori and Sudachi Analysis plugins are available for domains running OpenSearch versions, and are available in the Amazon Web Services China (Beijing) Region, operated by Sinnet, and the Amazon Web Services China (Ningxia) Region, operated by NWCD.

For more information about the new plugins, please see the documentation.  To learn more about Amazon OpenSearch Service, please visit the product page.
