Hi!
By default there is an option enabled, which basically allows results that does not have terms from the selected taxonomy for filtering. If you turn off this option, then only results that has the terms from the filter will be allowed: https://i.imgur.com/yZbi3Tv.png
The live search will only trigger when no keyword is entered, if the character count option is set to the default 0. You can change it here: https://i.imgur.com/Lm82oed.png
