Ability to exclude particular Community topics in Help search results for all users

Hi everyone. A feature that would be really useful would be the ability to have some control over what Community content displays in the search results of our Help centre for all users.

We're considering starting a more social type of topic for introductions in our Community at the moment, but don't want it to impact on the self-service purpose of our forum and be the cause of irrelevant information potentially clogging Help search results.

I understand that visibility settings can be set for admin agents and managers, but the ability to also restrict visibility on some for all users would be great. 

Is this something that might be in the pipeline, or that anyone else would like to see?
