Usually if I need a certain engine I just guess the bang and it's usually supported and correct. !gm for google maps, !tineye for tineye, !wayback for the wayback machine...

Setting DuckDuckGo as the search engine for your browser's address bar means all these bangs work right there whenever you open a new tab.

    !hn does something or another

!ddg google

Or if you are feeling lucky:

!!ddg google

:)

You are linking to a ~5 year old thread that is discussing the state of things well before google switched everything over to ssl.

I can only see this as a good thing. If I want local search results, I'll add local qualifiers like "USA", "Texas", "Houston"

Now if I type "h my-search" into the omnibar, it goes to google.com/search?q=site%3Anews.ycombinator.com+my-search which gives me only Google search results from HN.

This is using google's algorithm (not the search bar built into whichever website like DDG) which is still the best, especially if you constrain it to one domain name. I also don't have to type the "!"

The prefix messes up google's text prediction. I guess no one from the chromium team is using this feature, since it would be trivial to fix.

'<Song name> !' or '<song name> youtube !' takes you right to it.

I'd love a feature that opens the first result on a search engine like wikipedia does by default. Biggest use case for me would be imdb but there would be others.

DuckDuckGo has that by using a backslash, a space and a search term (\ bed intruder youtube) or an exclamation a space and the search term (although I believe the former is the official way now). I use it all the time, it's like a superpower.

Now that I've learned that !a works for amazon.com and duckduckgo.com gets affiliate revenue that way, then that's how I'll search amazon from now on. Need to boost up the underdog that cares about privacy, because google surely doesn't.

If you're on Google as your default search engine, it's not so convenient to see other engine's results (plus you're being tracked all the time).

Sounds like they have changed a lot since then, so I'll probably give it another shot.
