Bangs dont 'get specific results' - they're shortcuts to let you do site-specific 'searches', on that site.

So, if I want to check the versions of haproxy in the various Debian suites, then `!dpkg haproxy` would take me to https://packages.debian.org/search?keywords=haproxy.

If I just want general results about HAproxy, that isn't what a bang is for.
