It might have changed in newer versions, but I don't see why. It used to be possible to do this without restarting — you could request a rescan just by pressing a button in AdminFE and there was a mix command too, I just can't recall it off the top of my head. You had to reload the page for autocompletion to work in PelormaFE — which of course wasn't necessary in Bloat.
The rescan could timeout if you have lots of them though — often the case with anemic instances, such as my Breloma.
