spotlight can run custom scripts, you just have to put a “script editor” file in you folder -so spotlight can index it- (iCloud folder for me is the better) then command + space, type some part of the name, highlight it an hit enter. Can be done in AppleScript or Javascript.

after adding a site to the whitelist.txt file and restart the Pi, the site is still blocked, you have to run gravity.sh to unblock the site
