Hello Ernest,
I have managed to display the BuddyBoss members of a specific WordPress Role. The overlapping role is WCFM Vendor which appears in search results, and changing the link to BuddyPress profile did the trick. Thanks.
I was wondering about the avatar that shows in the result. Currently it is set to show a Gravatar, but we have turned off this setting in BuddyPress. Is it the ajax search that is looking for a gravatar or is profile image in the result a default gravatar?
