When you set the locales for your application, the MDEX Engine applies a language analysis to records, record properties, dimension tags on records, or to all record data processed by an MDEX Engine. A language analysis is a set of rules that the MDEX Engine applies when it indexes text in any of the languages in a particular language group.

You configure the locales of an application as part of the search Index configuration. The locale settings can be found in /config/import/searchIndexConfig/_.json. The JSON properties defaultLocale and locales are used to configure the locale attributes. You can configure the locales by using the REST API.

For detailed information about configuring locales, see the Oracle Commerce Guided Search Configuration Guide.
