I think I see what you are looking for @wpuncharted. I’m looking for the same:
A search that not only gives you elements of content (doscs, pages, wiki, posts, files, forum posts) but also elements of “structure” (people, groups, forums themselves or forum topics, projects if collabpress etc…).
Tag should do that, but it seems tags function in silos. It would be great to have a sitewide tagging function that pulls together on a page all the elements including members, groups, projects etc with that tag.
I posted on this with no reply yet: https://commonsinabox.org/groups/help-support/forum/topic/members-tags-sitewide-tags/
Hoping this has a solution.
