How is searching encrypted data not going to be used for exfiltration? What a terrible idea.

I’m sure you can name benign useful things you could use it for. But it seems to me you’re blatantly overlooking the obvious flaw.

There is no getting around doing search on encrypted data reducing the level of secrecy. To have an even minutely useful search result, some information within the searched corpus must be exposed.
