How to include accordion content in Search Results?

I have created a FAQ page with three accordions containing a lot of questions and answers. However when I use the standard search function on my site to search for some of the terms that appear in the FAQs, they are not showing up in the search results. This is quite a key page on the site, and it is important that the content on it shows up in search results. How can I make these accordions searchable? Thanks!
