Facet filter on multilingual field

MongoDB Atlas Atlas Search
,
#1

Hello.

We are trying to build a facet search, based on MongoDB Atlas search.

In our use case, we have multiple attributes on a document, where each attribute has a value and the localized values for multiple languages:

attribute: {
  value: string,
  valueDe: string,
  valueEn: string,
  valueIt: string
}

We would like to make the facet query on attribute.value directly, but get also the localized values, to display them in the frontend.

Is there currently a performant way to achieve this?

It doesn’t seem to be good practice to make the facet query on the localized field directly, because we could potentially get different results, depending on the selected language.
Do you have any experience and advice with this use case?
