I happened to stumble on this: the DuckDuckGo search engine will take you directly to a DragonFly man page, if you type ‘!dfman’ at the start of your query. For instance, “!dfman hammer“.
DDG is a great search engine anyway, I use it for the vast majority of my internet searches and works fine.
ddg make a good work, he also has a search engine for .*\.onion sites (tor) (yes it’s not related to df but it’s nice)
