Two Search Databases | WordPress.org

I’m looking to duplicate my blog search index into my courses index. Is this possible?

I’m also concerned that I want it to be totally separate, meaning that no free blog content will show up in the blog search index on the free side of my website, the same goes for paid content showing up when someone searches using the blog index.

I’ll want the user to be able to search for titles of the page, course and PDF downloads.

I’m also using MemeberPress as my paid content plugin.
