Filter the searched solutions by folder visibility

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 only the articles that has folder visibility equal 1 (which means visibility for all users).

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