I run all my searches in FZF as I edit my notes in Vim. See https://share.cleanshot.com/x9ZkfBQQ -- Will require some tinkering but it runs the inference/search server so the searches are fast. It's deployed to Modal.com

# FZF quotes field names so I can't easily get preview to work otherwise
cd "$ZK_PATH"
