Not sure if they promptly rebranded, but the search is called Torch actually. Here's a screen of an example search [1]. Note the query time - it's quite slow.
Torch is an entirely different search engine at a different domain; I run TorSearch and built it from scratch partially because of how terrible my experience using Torch was.
