Hi!
It’s actually a new feature from plugin version 4.0 (or 4.5?) if I remember correctly the version number of this. It might be turned off by default.
To enable, go to the General Options -> Behavior and turn on the “Trigger search when changing a facet on settings?” option: https://i.imgur.com/b9hn27H.png
This is yet missing from the documentation, sorry about that – but I’m working on an “easy mode” switch and a quick “option search” feature to look up an option on the plugin back-end, there are simply too many of them.
Best,Ernest Marcinko
