I used to know of a search engine that supported a bunch of added functionality for searching some selected popular sites. Like "wp whatever" would search just Wikipedia. It supported many man little command shortcuts.

It was popular among dwm/i3 users, and I have forgotten it :(

I was a fan of MacOS performing searches with Command + Spacebar, so on Linux I scripted a similar popup-prompt that would open Firefox and feed my input to this search engine.

will take you directly to Wikipedia... [DDG offers] 13,505 bangs and counting...”
