Altering BP-community theme search function to search on added profile items

I added some fields to user profiles as part of an s2member configuration. The problem is, these additional fields don't get included as searchable fields when searching "Members." For instance, one of the fields is "company", but searching on a company name that is part of a member's profile information returns no results. How do I add these fields to what the "member" search is searching in?

Hopefully, there is some way for me to modify the search in my child theme functions file?
