A search engine via ethereum is not going to scale, is not easily upgraded, and will fall far short of any properly centralized search engine. If you want a competitve decentralized search engine, you're going to need a different technology.

I think that's why they talk about homomorphic encryption.
Homomorphic encryption as best I'm aware is more than a decade away from practical use. I believe the best libraries today have blowups of 100,000,000x in resource usage, meaning it's not even practical for basic crypto operations.
Multiparty computation makes some security sacrifices (breaks if M out of N people cheat, breaks undetectably iirc), but I think the blowup is less than 10x for some operations and less than 1000x for the others.
Still not pretty, but at least makes certain things possible. But not competitive search engines.
