In case anyone has problems with the searx(dot)be public instance, you can always find more public searx instances on searx(dot)space.
It has a list of more public instances and some onion TOR instances as well.
Recently I've had issues where searx(dot)be has not been able to load if I search something in the little web bar on the Firefox based browsers and sometimes have problems where it'll give me some sort of too many request errors, so I just heard to a different instance to solve it.
