This is one of the current 'tech' trends that I'm following, the idea of homomorphic encryption is really cool. I feel like there is a lot of real world applications for it, but I have failed to find them yet.
One of the big ones is internet searches. Also processing PII/HIPAA data.

How does this affect internet searches?

I really want to sarcastically say "blockchain homomorphic encryption", but, well, it's not necessarily a terrible idea, honestly. One can imagine some combination of the primitives in which you could prove that you added here the same amount you subtracted from there, that neither total is below zero, but for which the number actually transferred is encrypted. The current use case for something like BitCoin is often…

I think this is what zcash already does.

The "Confidential Transactions" scheme for cryptocurrencies uses homomorphic encryption. The idea is that you can prove that the encrypted input and output amounts in a transaction balance to zero, without having to actually reveal what any of those amounts are.

You want authenticated encryption instead. https://tonyarcieri.com/all-the-crypto-code-youve-ever-writt...
You can sort of build something authenticated on top of a homomorphic cryptosystem, but it's kind of a hack: https://paragonie.com/blog/2017/12/assuring-ciphertext-integ...
Homomorphic encryption is cool, but it's not the sort of thing most developers will want to use in their apps. Most cryptography failures (BEAST, CRIME, the Apple iMessage attack, etc.) that allow plaintext recovery are the result of chosen-ciphertext attacks.

zCash uses zk-SNARKs for secret transactions. Which are awesome. But homomorphic encryption allows general-purpose computation.
