Search results will reflect the permissions of the modules and categories on the platform. So if you have a private category, those results will not be visible in logged-out searches (for public or hybrid communities)
In future search UX improvements, I strongly recommend that logged-out, public search results have a default call-to-action to log-in for full results.
Benefits:
- A better experience for the end user.
- Increased likelihood of logins and active users for the community managers
I can imagine that there might be a very limited number of fully public communities that this might be irrelevant for. However, the phrasing tool and custom CSS could easily amend that.
Comparatively, the number of communities with hybrid settings, could greatly benefit from this. Inserting the call out is much more difficult than hiding it.
