Nostr search engines are great. Any way to filter out bots?

I have found some keyword results basically are ddosed by bot results.

not really, other than using ever more esoteric keywords, which becomes a cat and mouse game. I wish we could search our personal feed though. At least twitter has that. let's you search your personal feed. Just enter your npub along with your search query.

Ideally that would be solved by relays that implement nip-50.
