How positioning in App Store works in terms of localization?

How does providing localized descriptions for iOS application affect its positioning in search results?

Of course, it will increase visibility for localized keywords, but let's assume that a German Apple Id is looking for an English keyword.

Will the application be higher in results if it provides German localization (even if the search phrase is in English and does not occur in German localization)?

In general, what is taken into account when presenting search results in the App Store? (only content for the user's current region assigned to Apple ID?).

If I have "some position" in search results in X region and I will remove localization for Y region will it have any impact on my position in X?
