Filter the searched solutions by language code

Hello,
Hope you are doing well.
I'm working in a project that integrates with Freshdesk.
We are having some limitations with Freshdesk API and we would like to propose some improvements:

It's related to the endpoint /api/v2/search/solutions?term=[keyword]
We would like to retrieve the articles that has translation to a given language. Now it's a slow process get this result because we need to call the endpoint /api/v2/solutions/articles/[id]/[language_code] to every searched solution. 

This feature is highly relevant. 
I appreciate your help,
Warm regards
