I have done multiple searches on Groups.io. From that empirical data I have surmised that the text of the post is not being searched, only the title and hashtags. That is not really helpful unless everyone adds hashtags to the message title. I think that is too much to ask of the new user, and I do not know how to do so in a reply. Maybe we need "Potential Elmer" training as well
Until I learn more, I will try to share what I think I know. I only ask that corrections be respectful and not flaming.
