The Oracle ATG Web Commerce platform includes an implementation of the VariantProducer interface, atg.repository.search.indexing.producer.LocaleVariantProducer, for generating variant documents for different locales. This class has a locales property where you specify the list of locales to generate variants for. For example:

locales=en_US,fr_FR

You specify the VariantProducer components to use by setting the variantProducers property of the IndexingOutputConfig component. Note that this property is an array; you can specify any number of VariantProducer components, and the IndexingOutputConfig will generate a separate variant for each possible combination of values of the variant criteria. For example, suppose you use LocaleVariantProducer and the locales property is set as shown above. If you add a second VariantProducer that creates three variants (1, 2, and 3), the total number of variants generated for each repository item would be six (French 1, English 1, French 2, English 2, French 3, and English 3).
