Amazon OpenSearch Service now allows you to use custom dictionaries with the IK (Chinese) Analysis plugin. With support for custom dictionaries, you can use your preferred keywords and synonyms with IK Analyzer to tailor search results to suit your business needs.

Previously, you could use the IK Analysis plugin in Amazon OpenSearch Service with the default dictionary that came with the plugin. Now, you can upload your dictionary files as custom packages using the Amazon OpenSearch Service console or APIs, and associate them to a domain, which will then be picked up by the IK Analysis plugin. You can also update these dictionary files dynamically, without the need of a blue/green deployment. For more information on using custom packages, please refer to the documentation here. For information on the plugins in Amazon OpenSearch Service, and supported versions, please see the documentation here.

Custom dictionary support for IK (Chinese) Analysis plugin is available for Amazon OpenSearch Service domains in the Amazon Web Services China (Beijing) Region, operated by Sinnet, and the Amazon Web Services China (Ningxia) Region, operated by NWCD.
