Paginated Solution Article Search API Doesn't Return "Link" Header

When performing a paginated search against the solution article search API endpoint, the number of results returned match the per_page parameter, but the returned headers don’t include the “Link” header with the url for the next page. Is this by design? If so, how do I perform pagination on search results.

/api/v2/search/solutions?term=account&per_page=10&page=1

I am also facing the same issue while fetching groups. It returns 30 group names, but the header is empty
