Contents of component not searchable or viewable in a WordPress Search

Can you please tell me what can be done to make the contents of a component searchable and viewable in a WordPress search?

In short, we created a component called Staff Card, which contains the name and various pieces of contact information (phone, email, job title, etc.) for each employee. However, when anyone performs a WordPress search for an employee, none of the employee information contained within the Staff Card component appears in the search results.

What can be done to fix this issue? This is a pretty glaring issue, especially when we are using a number of other components that contain pertinent information and in this case where someone cannot search a site that contains hundreds of employees.

In another thread, someone mentioned that if the component had [cs_content_seo] that the output could be searchable. Can you please tell me how to add this to the component, so the contents can be searchable?

Due to the fact that this is an intranet, we cannot use a Google Search. It has to be a WordPress search.

Thank you for your assistance.
