Flex search utility not indexing authors

There's currently no feature that allows author names of articles to be indexed by the search utility. It only works if the byline is entered in manually as opposed to adding an author by registered user account with the CMS. The only way to access a curation of all of the author's articles is to find an article they wrote and click on their author name, where it prompts to a url address like this www.siteaddress.com/users/profile/authorfirstname%20lastname/
