Without having tested at our own community, it's a Pandora's box though. Unfortunately, the regular search is still no good for certain searches. I have trashed 6 pages of results before to get the relevant result at the top ... (and ever since, I've stopped doing that)
So my request from april 2017 still stands:- Give us the option to keymatch and promote Sticky Topics and / or topics with a certain moderator tag.
Either for regular search, live search, even related topics or all of them.
