It seems storm is no longer updated for years. So I found it’s actually really simple to implement Storm SSH’s searching feature via a simple function:

function sshgrep
  grep -i -E -C 3 $argv ~/.ssh/config.d/*
end

Usage:

ssh grep ixion
/Users/sparanoid/.ssh/config.d/server-aws.conf-  Port 22
/Users/sparanoid/.ssh/config.d/server-aws.conf-  User ssh-user
/Users/sparanoid/.ssh/config.d/server-aws.conf-
/Users/sparanoid/.ssh/config.d/server-aws.conf:Host ixion
/Users/sparanoid/.ssh/config.d/signcl-aws.conf-  HostName 11.22.33.44
/Users/sparanoid/.ssh/config.d/server-aws.conf-  Port 22
/Users/sparanoid/.ssh/config.d/server-aws.conf-  User ssh-user
