Amazon OpenSearch Service adds support for four new language analyzer plugins- Nori (Korean), Sudachi (Japanese), Pinyin (Chinese), and STConvert Analysis (Chinese) 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.

Nori, Sudachi, Pinyin, and STConvert Analysis plugins are available for domains running OpenSearch versions, and are available in all AWS regions globally where Amazon OpenSearch service is available. Please refer to the AWS Region Table for more information.

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