How to filter out a few inner objects from search query results

Hi,

I have the following schema and two documents and a search query on them. I want to know how can I only display specific language's names and descriptions in each of my search result. For example in the query result for below query, I get all the names and descriptions in all languages. But if I pass a locale as 'fr' I would like names and descriptions only in french. Not in any other languages.
Thanks,
