Does anyone know how (of if it is possible) to have a page in Statamic show up in search results for all the content shown on the page?

Specifically, if a collection item is shown on a specific page.

So, for instance, a page about Topic-1 has an area of the page where all the collection items about Topic-1 are displayed. I want the page that displays the collection items to show up in search results, not the collection items themselves with their individual routes.

I'm working on removing the individual collections, but I'm curious how to (and if its possible) to index a site page with the collection items that are visible on that page?

Maybe there is a way in the yaml searchable: to lists collections that might be visible on the page?

Any ideas?
