Generalised method for shortcuts to sites and site-searches?

[emacsomancer]

Is there a generalised method for creating (1) shortcuts to sites, e.g. C-c C-r to open "roots-archives.com", and (2), (perhaps more importantly), site-internal searches, e.g. C-c C-i + a search term $S to search imdb.com for $S?

(I'm trying to migrate from Conkeror to keysnail, and this is one feature I'm missing from Conkeror.)

We hope you find it informative.
This code search select word by eow.

key.setViewKey('C-\'', function (ev, arg) {
    gBrowser.loadOneTab(util.format("https://eowf.alc.co.jp/search?q=%s", encodeURIComponent(command.getClipboardText(true))));
}, 'goto_alc_from_selection_clipboard_in_tree');

Thanks @ncaq, that does help for one function I wanted.

Do you know if there is a good example of making a shell command like:

amazon high quality green tea

which would open up amazon and do a search for "high quality green tea"?

I don't use keysnail when it case.
I copy to clipboard high quality green tea, and search from firefox standard awesome bar.
I recommend see How to search IMDB, Wikipedia and more from the address bar | Firefox Help

I've tried this, but it's not ideal. There's no sort of autocompletion, so I can't do gitl TAB and have it complete gitlab and then type a search item.
