how to use ILocale?

Hi Team,

We are working on epi find upgrade v-13. The new language routing feature is added to the find entry if the content implements ILocale.

But we are not using a variation or page data for find index instead of using a customized index model. How to implement ILocale for our custom model? how to set the language to our custom model?

Any help would be appreciated.

Advance Thanks,
